Question

Instructions: Find the surface area of each figure, Round your answers to the nearest tenth, if necessary 12 yd. 3 yd. Surface Area: W?

Answer 1

REmember that

the surface area of a cylinder is equal to

SA=2(pi)r^2+2(pi)(r)(h)

we have

r=3 yd

h=12 yd

substitute

SA=2(pi)3^2+2(pi)(3)(12)

SA=18pi+72pi

SA=90pi yd2

SA=282.7 yd2
