Question

If the total surface area f a cylinder is thrice it's curved surface area,then find the height in terms of it's radius

Answer 1

Answer: height= radius/2

Step-by-step explanation:

given,

TSA = 3(CSA)

=2$\pi$r(r+h)=3(2$\pi$rh)

=r+h=6$\pi$rh

      2$\pi$r

=r+h=3h

=3h-h=r

=2h=r

=h=r/2

height=radius/2
