Question

If the circumference of the cylinder is 88cm and height is 42cm . find the volume

Answer 1

circumference = 88 cm
$2\pi \: r = 88 \\ r = 14$
h= 42 cm

$volume \: of \: the \: cylinder \\ = \pi {r}^{2} h \\ = \frac{22}{7} \times 14 \times 14 \times 42 \\ = 44 \times 14 \times 42 \\ = 25872cm \: cube$
