Question

The curved surface area of a cylinder is 264 m² and its volume is 924 m³. The height of the pillar is ​

Answer 1

Answer:

6 m

Step-by-step explanation:

csa = 2πrh

volume = πr^2 h

dividing volume by csa we get

r/2= 7/2

r=7

putting r in csa formula we get

264=(22/7)*7*2*h

h=6 m

Answer 2

Answer:

Given: Curved Surface Area of cylinder = 264m²

Volume of cylinder = 924m³

CSA of cylinder = 2πrh

264 = 2× 22/7 × r × h

r×h=42

h= 42/r. ..............(1)

Volume of cylinder = πr²h

924= 22/7 ×r² × 42/r

924= 22/7 ×r×42

r= 924×7/22×42

r=7m.

Radius is 7m

diameter is 14m

Height of cylinder = 42/7 =6m
