Question

find the volume of a cylinder having a height of 21cm and an area of Base as 138cm².​

Answer 1

Answer:

2898cm³

Step-by-step explanation:

base of the cylinder is a circle=πr²=138

volume of the cylinder=πr²h         (where h=21)

=138*21

=2898cm³

Answer 2

Dimensions of a cylinder :

$Height (h) = 21 \:cm$

$Area \: of \: the \: base (A) = 138 \:cm^{2}$

$\boxed { \pink{ Volume \: of \:a \: cylinder (V)= A \times h }}$

$= 138 \times 21$

$= 2898 \:cm^{3}$

Therefore.,

$\red{ Volume \: of \:the \: cylinder}$

$\green {= 2898\:cm^{3} }$
