Question

PLEASE? =)
Jake has two similar cylindrical pipes. The radius of the first cylindrical pipe is 5 cm. The circumference of the second cylindrical pipe is 20π cm.

The volume of the second cylindrical pipe is how many times greater than the volume of the first cylindrical pipe?
Answer

3

4

5

8

Answer 1

volume =\[\pi * radius ^{2} * height\]
you are given the circumference of the second pipe and from there we can find the radius for the second pipe
\[20π =2\pi r1\] ......
using the equations above the answer is 4
