Answer:
h = 8.00 inches , which is answer B
Step-by-step explanation:
The formula to calculate the Volume V of a cone is:
V = 1/3*pi*r²*h
Given:
V = 33.5 in³ pi = 3.14 and r = 2 in
This time the Volume is given, but you need to calculate the height h. So let's rewrite the formula, so it starts with h =
V = 1/3*pi*r²*h
multiply left and right of the = sign by 3
3/3*pi*r²*h = 3*V
divide left and right of the = sign by pi*r²
h = 3*V/(pi*r²)
V = 33.5 in³
pi = 3.14
r = 2 so r² = 4 in²
h = 3*33.5/(3.14*4)
h = 8.00 inches , which is answer B
