Question

Csa of the cylinder is 264metresq and its volume is 924metrecube find the ratio of height to its diameter

Answer 1

CSA=2πrh=264
πrh=132------------------------------------(1)
Volume =πr²h=924
=πrh×r=924-------------------------------(2)
USE (1) in (2)
=132r=924
=r=7m-------------------------------------------(3)
use (3) in (1)
22/7×7×h=132
22h=132
h=6m
ratio of hieght to diameter=6:14
or 3:7
