Use the following formula:- [latex]SA=2 \pi rh+2 \pi r^2[/latex] r = radius h = height Substitute for the formula:- r = 5 [latex]SA = 2 * \pi *5*h+2* \pi *5^2[/latex] 2 = 5 [latex]SA = 2 * \pi *r*2+2* \pi *r^2[/latex] [latex]SA= 2* \pi *5*2+2* \pi *5^2[/latex] Solve:- [latex]SA= 2* 3.14 *5*2+2* 3.14 *5^2[/latex] SA = 2 × 3.14 × 5 × 2 + 2 × 3.14 × 25 SA = 6.28 × 5 × 2 + 2 × 3.14 × 25 SA = 31.4 × 2 + 2 × 3.14 × 25 SA = 62.8 + 6.28 × 25 SA =  62.8 + 157 SA = 219.8 SA = 219.8 yds The surface area of this cylinder is 219.8 yds (yards)
