Question

Area of curved surface of a cylindrical pole is 264 m² and its volume is 1848 m³. what is the height of the pole? (use π = 22/7)

A.

4 m

B.

3 m

C.

5 m

D.

6 m

Correct option is B

22/7 rrh = 1848
Or, rrh = 588
Rx42 = 588 …………..(by equation (i))
R = 14m
In equation 1
Rxh = 42
Substitute value of r = 14 x h = 42
So, h = 3m
