Question

Im in desperate in need of help

Answer 1

(2.) V = 1,536
`\pi` mm^3; (3.) V = 1,943.9 mm^3

Explanation:

The formula for volume of a cylinder is V =
`\pi r^(2)h`

For Problem 2, we have V =
`\pi * 8^(2) * 24`

V = 1,536
`\pi` mm^3

For Problem 3, we have V =
`\pi` *
`((15)/(2))^(2)` * 11

V = 1,943.86 = 1,943.9 mm^3
