Find the surface area for a cylinder with a height of 20 and a radius of 6. Use 3.14 for pi and round to the nearest whole number.

Question

180 ft
720 ft
433 ft
135 ft
I thinks it is 720 ft.

Answer 1

2π(6^2+6*20) = 980

so, maybe you don't want the ends. Just the lateral area is

2π(6*20) = 754
