Question

6 The radius of the base of a cylinder is 39 in. and its height is 33 in.. Find the surface area of the cylinder in terms of s.​

Answer 1

17650 in².

Explanation:

Given that the base of cylinder is 39 inch and it's height is 33inches . We need to find the surface area of the cylinder . So we know the TSA of cylinder as ,

`\bf\implies TSA_((cylinder))= 2\pi r ( r + h ) \\\\\bf\implies TSA_((cylinder))= 2\pi 39 ( 39 + 33) in.^2\\\\\bf\implies TSA_((cylinder))= 2* (22)/(7)* 39 * 72 \\\\\sf:\implies \boxed{\red{\bf TSA_((cylinder))= 17650 in^2}}`
