Question

The circumference of the base of a cylinder is $132$ cm and its height is $25$ cm The volume of the cylinder is

• A. $34650$ $c{m}^3$
• B. $34640$ $c{m}^3$
• C. $34450$ $c{m}^3$
• D. None of these

Answer 1

Answer: (A)

$34650$ $c{m}^3$

Volume of cylinder = $=\pi r^{2}h$
According to the question, $2\pi r=132$
$\Rightarrow 2\times \frac{22}{7}\times r=132$
$r=21cm$
Volume $=\frac{22}{7}\times 21\times 21\times 25=34650c{m}^3$
