Question

The curved surface area and the total surface area of a cylinder are in the ratio 1 2 if the total surface area of the right cylinder is 2464 cm^2 then its volume is

Answer 1

GIVEN

CSA : TSA = 1:2

CSA OF CYLINDER = 2(pie)rh

TSA OF CYLINDER=2(PIE)r(r+h)

h:(h+r) = 1:2

BY COMPARING WE GET

h=1 and r=1

VOLUME = (PIE)(r)^2 h

= (pie) (1)(1)

=(pie)
