Question

find the volume of cylender night is 7cm and radius is 5cm

Answer 1

r = 5 cm
h = 7cm
then,
vol. of cylinder =
$\pi \: {r}^{2} h$
=22/7 X 5cm X 5cm X 7cm
=22 X 25cm^2 X 1cm
=22 X 25cm^3
$550 {cm}^{3}$

Answer 2

Solution ●●●●
______________

Given,

Height ( h ) = 7 cm

Radius ( r ) = 5 cm
_________________

$Volume \: \: \: \: of \: \: \: \: the \: \: \: \: cylinder$

$= \pi \: rh$

$= (\frac{22}{7} \times 5 \times 5 \times 7) \: \: {cm}^{3} \\ \\ = 550 \: \: {cm}^{3}$
