Question

If r = 8 units and h = 10 units, what is the volume of the cylinder shown above? Use 3.14 for .

Answer 1

The formula of the volume of a cylinder:


`V=\pi r^2H`

We have:
r =8 u. ; H = 10 u.

substitute:


`V=\pi\cdot8^2\cdot10=\pi\cdot64\cdot10=640\pi\ u^3\approx640\cdot3.14=2009.6\ u^3`
