Question

find the volume of cricular cylinder of height 35 cm whose curved surface area is 3375 sq cm

Answer 1

Hlo friend.. Cutiepie Here..

Here is ur answer :

Height h of cylinder = 35 cm

Curved surface area of cylinder = 3375 cm²

First we have to find radius of cylinder.

Let the radius be r.

According to question..

$2\pi rh = 3375$


$2 \times \frac{22}{7} \times r \times 35 = 3375$


$44 \times r \times 5 = 3375$

$220 \times r = 3375$

$r = \frac{3375}{220}$

$r = 15.34$


Radius r of cylinder = 15.34 cm

_______________

Volume of cylinder

$\pi {r}^{2} h$

$= \frac{22}{7} \times 15.34 \times 15.34 \times 35$

$= 22 \times 15.34 \times 15.34 \times 5$


$= 25884.716$


Volume of cylinder = 25884.716 cm³.
