1. The measurements you need to find the volume of a cylinder are the radius of the base of the cylinder and the height of the cylinder.
2. The radius is 4
3. The 3D shape will form a full cylinder.
4. To calculate the volume of a cylinder we use the formula V = πr²h which is = π(4²)(2) = 3.14 × 16 × 2 = 100.48 cm³
5. The formula for a refraction will be (πr²h) / 2
6. From the formula in part E, the approximate volume of a refraction is (3.14 × 4² × 2)/ 2 = 50.24 cm³
How do you find the radius of the base of the cylinder and the height of the cylinder as far as calculating the volume of a cylinder is involved?If you have been givn the volume of a cylinder and its height, you can use the formula for the volume of a cylinder to solve for the radius. Rearange the formula to r = sqrt(V / (πh)).
If you know the surface area of a given cylinder and height, you can find the radius using the formula for cylinder surface area (A = 2rh + 2r2). Rewrite the formula as r = (A - 2h) / (2.

A shoe repairman is working with his assistant, who takes 1.5 times as long to repair a pair of shoes.
Together they can fix 10 pairs of shoes in six hours. How long does it take the repairman to fix one pair
of shoes by himself?
Answer:
1/2 or 0.5 hours
Step-by-step explanation:
r = time for repairman to fix one pair of shoes.
a = time for assistant to fix one pair of shoes.
a = r×1.5
x×r + y×a = 6
x = number of pairs of shoes repaired by repairman.
y = number of pairs of shoes repaired by assistant.
x+y = 10
y = 10-x
x = y×1.5 (based on the a/r ratio : as the assistant needs 1.5 times longer, the repairman will have repaired 1.5 times more pair of shoes in the same time)
y = 10 - y×1.5
y + y×1.5 = 10
2.5×y = 10
y = 4
=> x = 6
6×r + 4×r×1.5 = 6
6×r + 6×r = 6
12×r = 6
r = 6/12 = 1/2 or 0.5 hours
Joseph and Mark have $230. Joseph and Kevin have $130. Mark had 3 times as much money as Kelvin. How much money does Kelvin have?
Answer:
Step-by-step explanation:
Let's call Joseph "J", Mark "M", and Kevin "K" for ease. We need a system of equations to solve this, 3 equations for 3 unknowns. The first equation is
J + M = 230. The second equation is
J + K = 130. The third equation is
M = 3K. Sub that 3K into the first equation and get
J + 3K = 230. Now take th second equation and solve it for J:
J = 130 - K. Now sub 130 - K into the re-written first equation to get a whole new equation in terms of K only:
130 - K + 3K = 230 and
2K = 100 so
K = 50
Kevin has $50

Answer:

Answer:
area of shaded part = 512 ft^2
Step-by-step explanation:
find area of rectangle
length = 32 +8
=40 ft
breadth = 8 + 8
=16 ft
area of rectangle = l*b
=40*16 ft
=640 ft
since there are two square .we should find the area of two sqaure.
length = 8 ft
area of square = l^2
=8^2
=64 ft^2
area of another square = l^2
=8^2
=64 ft^2
area of shaded part = area of rectangle - (area of square + area of square)
=640 -(64 + 64) ft^2
=640 - 128 ft^2
=512 ft^2

13. The function y=16 cos(x)+k has a minimum value of -4. What is its maximum value? Explain.
Answer:
It's maximum value is 28.
Step-by-step explanation:
Cosine function:
The cosine function has the following format:
[tex]f(x) = A\cos{x}[/tex]
The difference between the maximum and minimum point is 2A.
y=16 cos(x)+k
A = 16, so 2A = 32.
Minimum value of -4. What is its maximum value?
[tex]M - (-4) = 32[/tex]
[tex]M + 4 = 32[/tex]
[tex]M = 32 - 4 = 28[/tex]
It's maximum value is 28.

Find the volume of a right circular cone that has a height of 18.8 m and a base with a
radius of 19.3 m. Round your answer to the nearest tenth of a cubic meter.
Step-by-step explanation:
Height of the right circular cone = 18.8 metres
And base is 19.3 metres
Volume of the right circular cylinder is given by,
= πr²h
= 3.14 × (19.3)² × 18.8
= 21999.98(approx.) cubic metre
Rounding off nearest tenth
= 21999 cubic metres
The volume of the right circular cone is 280,199.5 m³
What is a right circular cone?
'A right circular cone is a cone where the axis of the cone is the line meeting the vertex to the midpoint of the circular base.'
According to the given problem,
Height = 18.8 m
Radius = 19.3 m
Volume of right circular cone = [tex]\frac{\pi r^{2}h }{3}[/tex]
= [tex]\frac{\pi * 19.3^{2} * 18.8}{3}[/tex]
= 280199.499 m³
= 280199.5 m³
Hence, we can conclude that the volume of the right circular cone is 280199.5 m³.

Answer:
b= (3z-6)/(1+3z)
Step-by-step explanation:
z=(-b+6)/(3b-3)
cross multiple
z(3b-3)=-b+6
open the bracket
3bz-3z=-b+6
make -b the subject of the formula
-b = 3bz-3z-6
-b - 3bz = -3z - 6
factorize the left hand side...
-b(1+3z) = -3z-6
make -b the subject of the formula again
-b = -(3z-6)/(1+3z)
cancel the minus at both sides...
b = (3z-6)/(1+3z)
Answer:
b = [tex]\frac{3z + 6}{3z+1}[/tex]
Step-by-step explanation:
Simply solve for "b" , so the formula will be
b = .....
z = [tex]\frac{-b+6}{3b-3}[/tex] ( b > 0 )
z(3b - 3) = - b + 6
3zb - 3z = - b + 6
3zb + b = 3z + 6
b( 3z + 1 ) = 3z + 6
b = [tex]\frac{3z + 6}{3z+1}[/tex]
Find the area of this triangle in square centimeters .
Step-by-step explanation:
The answer is 24 I think.
using the formula for finding the area of a triangle, which is....
Area= b times height divided by 1/2 or 2
First step is to multiply 6 which is the base by the height 8 to get 48. Then 48 divided by 2 is 24.
Step-by-step explanation:
the area of the triangle can be find by using the heron's formula...
that is:
√s-a×s-b×s-c
So,
a=8cm,b=6cm,c=10cm
Semi perimeter= 8+6+10/2=24/2=12
√12(12-8)(12-6)(12-10)
=√12×4×6×2
=√ 2×2×3×2×2×2×3×2
= √2×2×2×3
= 12 cm...

5. In the triangle ABC, M is the midpoint of [AB] and N is the midpoint of [CM].
Find the coordinates of N. Given that A(-1,3), B(7.-3) and C(1,6).
Answer:
The coordinates of the point N is (2,3)
Step-by-step explanation:
For us to find the midpoint between two points
We use the midpoint formula which is;
(x,y) = (x1 + x2)/2, (y1 + y2)/2
We start by finding the midpoint of AB to get the coordinates of the point M
A(-1,3) and B(7,-3)
(x,y) = (-1 + 7)/2, (3-3)/2 = (6/2,0/2) = (3,0)
Now that we have the coordinate of M, we can find the midpoint of CM to get the coordinates of N
C(1,6) and M (3,0)
(x,y) = (1 + 3)/2, (6+0)/2 = (4/2, 6/2) = (2,3)
