A cylinder has a radius of 3.2 meters its volume is 190 Cubic meters find its height to the nearest 10th of a meter
Answer:
volume = pi r^2 h
or, 190 = pi (3.2)^2 h
or, 190/10.24 = pi h
or, 18.56 = 22/7 h
or, 18.56×7/22 = h
thus , h = 5.9037

The correct relationship between the pair of angles m ∠AXC and m ∠BXC are,
A. They are supplementary angles,
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
Measure of angle m ∠AXC and m ∠BXC are,
m ∠AXC = 100 deg.
m ∠BXC = 80 deg.
Hence, We get;
m ∠AXC + m ∠BXC
= 100 + 80
= 180 degree

fill in blanks to write the function when x=3 h(x)=-4-7, when x=3:
h(__)=__
Answer:
h(x)= -4x-7, when x=3
Answer= h(3)= -19
Step-by-step explanation:
Substitute 3 for x in the function and simplify:
h(x) = -4x – 7
h(3) = -4(3) – 7
= -12 – 7
= -19
The value of the function h(x) = -4x - 7 at x = 3 will be -19.
What is function ?The function is defined as a relation between a set of inputs having one output each.
We have,
h(x) = -4x - 7,
So,
When
x = 3
So,
Substituting x = 3 in the given function,
i.e.
h(x) = -4x - 7
We get,
h(3) = -4 * 3 - 7
h(3) = -12 - 7
So,
h(3) = -19
So, the given function at x = 3 is -19.
Hence, we can say that the value of the function h(x) = -4x - 7 at x = 3 will be -19.

Answer:
u = 21
Step-by-step explanation:
WX = XY because (VW = VY)
WX = u + 42
XY = 3u
u + 42 = 3u
42 = 3u - u
42 = 2u
u = 42 / 2
u = 21
Answer:
u = 21
Step-by-step explanation:
Consider triangle XWV and triange XYV
XV = XV (common)
Angle XVW = Angle XVY (given)
VW = VY (given)
∴triangle XWV ≅ triange XYV (SAS)
∴ XW = XY (corr. sides, ≅ triangles)
u + 42 = 3u
u = 21
