Question

the ratio between the curved surface area and the total surface area of a right circular cylinder is 2 is to 3 find the ratio between the height and radius of the cylinder

Answer 1

Hope this ans will help u

Answer 2

CSA= 2πrh
TSA=2πr(r+h)
according to the question
CSA:TSA = 2:3
= 2πrh / 2πr(r+h)
h/r+h=2/3
cross multiple
3h=2x(r+h)
3h =2r+2h
3h-2h = 2r
h = 2r
now, in ratio 1:2
