the TSA of a solid right circular cylinder is 231cm^2..if CSA is two - third othe TSA,find the radius of he base.
Let the radius be r and height be h.
We are given,
Total surface area of cylinder = 231
------ (1)
Curved surface area
------ (2)
Substituting in equation (1), we get
Substituting the value of r in equation (2), we get
