What is the exact volume of a cylinder with a height of 8in and a diameter of 6 in
Andru [333]
<h3>♫ - - - - - - - - - - - - - - - ~<u>Hello There</u>!~ - - - - - - - - - - - - - - - ♫</h3>

➷ You would use the formula:

volume = \pi r^2*h

Substitute in the values:

(note: the radius is half the diameter)

volume = \pi (3)^2*8

Solve:

Volume = 226.1946711

I'm not sure how far you require it rounded, or if you want the whole value so I will just leave the entire value. If you need assistance with rounding it to specific figures, just comment down below and I'll help.

➶ Hope This Helps You!

➶ Good Luck (:
