Question

Please explain me as fast as can

Answer 1

hi!
here is your answer ! ! !

Radius(r) = 5cm.
Height(h)=21cm.

WE KNOW THAT,
$volume \: = \pi {r}^{2} h$

$volume = \frac{22}{7} \times {5}^{2} \times 21$

$volume = \frac{22}{7} \times 25 \times 21$

$volume = 22 \times 25 \times 3$
$volume = 1650 {cm}^{2}$

Therefore,
The volume of the cylinder is
1650 sq. cm.

hope this helps ! ! !#
