Question

Find the volume of cylinder whose curved surface area is 660 cm square and height is 15cm

Answer 1

Hii ☺!!

Here is your answer ✓ ✓ ✓

Height of cylinder ( H ) = 15 cm

Curved Surface area of cylinder = 660

2πRH = 660

2πR × 15 = 660

2πR = 660/15

2πR = 44

R × 22/7 × 2 = 44

R = 44 × 7 / 22 × 2

R = 7 cm.

Therefore,

Volume of cylinder = πR²H

Volume of cylinder = 22/7 × 7² × 15 cm³.

Volume of cylinder = ( 22 × 7 × 15 ) cm³.

Volume of cylinder = 2310 cm³.

☺ Hope it will help you ☺

Answer 2

We know that curved surface area of Cylinder=22/7 rh

660=22/7 rh

660×7/22=rh

210/15=r

14=r

r=7

Volume =22/7×7×7×15

=2310cu
