Question

the curved surface area of a cylinder pole is 264 metre square and its volume is 924 M cube find its height

Answer 1

Curved surface area = 264 m square

➡ 2πrh = 264

➡ 2*22/7*r*h = 264

➡ 44/7*rh = 264

➡ rh = 264*7/44

(264/44 = 6)

➡ rh = 6*7

➡ rh = 42



Volume = 924 m cube

➡ πr^2h = 924

➡ 22/7*r*r*h = 924

➡ 22/7*r*42 = 924

➡ 22/7*r = 924/42

➡ 22/7*r = 22

➡ r = 22*7/22

➡ r = 7


As r*h = 42
r = 7
=> 7*h = 42
=> h = 42/7
=> h = 6


Hence height (h) = 6m
