Question

The volume of cylinder is 49896 cm^3 and its csa is 4752 cm^2 ,then its radius is

Answer 1

therefore radius of the cylinder is equal to 21cm

Answer 2

The radius of cylinder is 21 cm

Step-by-step explanation:

Curved surface area of cylinder = $2 \pi r h = 2 \times \frac{22}{7} rh$

We are given that Its curved surface area is 4752 sq.cm.

So, $2 \times frac{22}{7} \times rh=4752$

$rh= \frac{4752 \times 7}{22 \times 2}$

rh=756

Volume of cylinder =$\pi r^2 h = \frac{22}{7} \times r \times rh = \frac{22}{7} \times r \times 756$

We are given that The volume of cylinder is 49896 cubic cm

So,$\frac{22}{7} \times r \times 756 = 49896$

$r=\frac{49896 \times 7}{22 \times 756}$

r=21

Hence The radius of cylinder is 21 cm
