Question

the curved surface area of a cylinder kal period is 264 m square and its volume is 924 M cube find the diameter and height of the pillar

Answer 1

Hi ,

Let r and h are the radius and height of the

cylinder ,

CSA of the cylinder = 264m²

2πrh = 264-------( 1 )

Volume of the cylinder = 924 m³

πr²h = 924 --------( 2 )

Divide ( 2 ) with ( 1 ) , we get

( πr²h ) / ( 2πrh ) = 924 / 264

r /2 = 7/2

r = 7 m

Diameter ( d ) = 2r = 2 × 7 = 14 m

Substitute r = 7 m in equation ( 1 ) , we get

2πrh = 264

2 × ( 22/7 ) × 7 × h = 264

h = 264 / ( 2 × 22 )

h = 6 m

I hope this helps you.
