Question

A cylinder measures height equal to $7$ cm and diameter as $4$ cm. Then find the volume of a cylinder.

• A. $63.56c{m}^3$
• B. $76.96c{m}^3$
• C. $80.09c{m}^3$
• D. $87.96c{m}^3$

Answer 1

The correct option is D $87.96c{m}^3$

We have,

$h=7cm$

$d=4cm\Rightarrow r=2cm$

We know that the volume of the cylinder

$=\pi r^{2}h$

So,

$=3.14\times 2^2\times 7$

$=3.14\times 4\times 7$

$=3.14\times 28$

$=87.96c{m}^3$

Hence, this is the answer.
