Question

A cylinder-shaped drainage pipe 66 in. long measures 25.12 in. around.

What is the volume of the drainage pipe?

Enter your answer as a decimal in the box. Use 3.14 for π.

Answer 1

v=hpir^2

tricky, they didn't give us radius
they just gave circiufmerece

c=2pir
25.12=2pir
divide by 2 both sides
12.56=pir
divide by 3.14 both sides
4=r

subsitutet

v=hpir^2
v=66pi4^2
v=66pi16
v=1056pi
v=3315.84 cubic inches

Answer 2

Answer:

3315.84
