Find the area of a circle whose circumference is the same as the perimeter of a square of side 22 cm. (Take π = 22/7)
Answer:
Perimeter of a square=circumference of circle
4×22=2πr
44=πr
r=14
Area of circle=πr2
22/7×14×14
28×22
616
Answer:
176cm²
Step-by-step explanation:
Side of square = 22cm
Perimeter of square = 88cm
Circumference of circle = perimeter of square
2π r = 88cm
2 x 22/7 x r = 88cm
44/7 x r = 88cm
r = 88 x 7/44
r = 14cm
Area of circle = π x r x r
= 22/7 x 14 x 14
= 44 x 4
= 176 cm²

15. 2x(xy) =
16. r(s)(t) =
17. (r)(s)(t)(x)(y) =
18. (7x + 2Y) =
Answer:
7. 2(x + 4) + 10 =2x+18
8. 3(6x) + 4 = 18x+4
9. 10(xy) = 10xy
10. 5(x + y) =5x+5y
11. 2(rs) + 4(x) = 2(rs+2x)
12. 2(q) + 2(x + t) = 2(q+x+t)
13. 6(7t + 4s) = 42t+24s
14. 9(10x) + 10y = 90x+10y
15. 2x(xy) =2x^2y
16. r(s)(t) =
17. (r)(s)(t)(x)(y) =
18. (7x + 2Y) =

ahh please help, i need to determine the slope and y-intercept for each graph. I need to write the equation for the graph in slope-intercept form.
Answer:
Step-by-step explanation:
slope: m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
m = [tex]\frac{3-4}{4-2}[/tex] = - [tex]\frac{1}{2}[/tex]
y-intercept: b = 5
Equation: y = - [tex]\frac{1}{2}[/tex] x + 5

One way to add integers is by using a number line. ... Our first number is negative four (-4) so we move 4 units to the left. We then have plus negative three (-3) which is the same as subtracting 3 so we ... We do the same thing if we have a positive integer, but instead we move to ... You can also add integers and variables.

What is the Volume of the box 385 cubes?
Answer:You can calculate the volume of a box by multiplying length x width x height. Using the example of the single wall box this will be 102 x 102 x 102 which equals 1,061,208 cubic millimeters (㎣).
Step-by-step explanation:
The Volume of the box is 385/27 inch³.
What is Volume?The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.
Many forms have various volumes. We have studied the several solids and forms that are specified in three dimensions, such as cubes, cuboids, cylinders, cones, etc., in 3D geometry. We will discover how to find the volume for each of these shapes.
Length = 11/3 inch
width - 5/3 inch
Height = 7/3 inch
So, the Volume of cuboidal box
= l w h
= 11/3 x 5/3 x 7/3
= 385/ 27 inch³
Also, Number of small cube = Volume of box/ Volume of small cube
385 = Volume of box / (1/27)
Volume of box = 385/ 27 inch³
