Question

A 0.35cm long solid is in the form of a right circular cylinder. If it's radius is 1.25cm,find the volume of the solid

Answer 1

It is given that the solid is in the shape of a right circular cylinder.

Also, h = 0.35 cm and r = 1.25 cm

We know that,

$volume \: of \: a \: cylinder = \pi \: {r}^{2} h \\ \\ = 3.14 \times 1.25 \times 1.25 \times 0.35 \\ \\ = 1.71 {cm}^{3}$

Thus, the volume of the cylinder will be 1.71 cubic cms.
