Question

The height of a cylinder is 4m and its curved surface area is 52.8m². Find its volume​

Answer 1

Answer:

height of cylinder= 4m

CSA= 52.8m²

2πrh= 52.8

2 x 22/7 x r x 4 = 52.8

r= 52.8 x 7 / 2 x 22 x 4

r= 2.1 m

volume = πr²h

= 22/7 x (2.1)² x 4

= 55.44m³

hope it helps..

Answer 2

52.8 =2*22/7*R*4=0.47

volume= 22/7*0.47*0.47*4=.88
