Given a sphere, cylinder, cone of same radius find ratio of theri curved surface area

Cone does have a csa
It is their
Cone has csa that is pi r l


Csa of sphere=0
csa of cylinder=2 \pi rh
csa of cone= \pi  r^{2}

ratio between sphere,cone and cylinder=0:1:2h
1 5 1
is csa of sphere
it doesn't have curve
Curved surface area of sphere =4
curved surface area of cylinder =2r(2r) =4
curved surface area of cone =rl
ratio of their curved surface area  =4r²:2rh:rl
                           = 4:4:
