Question

What is the volume of a 24 mm tall cylinder that has a diameter of 6mm?

Answer 1

Height (h) = 24 mm

Diameter = 6 mm

Radius (r) =
`(6)/(2)` = 3 mm

Area =
`\pi r^(2) h = \pi * (3)^(2)* 24 = \pi *9 * 24 = 216 \pi` = 216 * 3.14 = 678.24 mm²

Answer 2

volume = PI x r^2 x h

using 3.14 for pi

3.14 x 3^2 x 24 = 678.24 cubic mm
