Question

Find the surface area of the prism or pyramid. Round to the nearest hundredth if necessary.

Answer 1

SA(surface area)

SA = 2xh + 2pi * r ^ 2

SA = 2pi * (8) * (4) + 2pi * r ^ 2

SA = 2pi * (32) + 2pi * (8 ^ 2)

SA = 2pi * (32) + 2pi * (64)

SA = pi(64) + pi(128)

SA = pi(192)

SA = 603.19 ft ^ 2

Answer 2

Answer: 602.88

Explanation:

2πr^2+2πrh

2(3.14)(8)^2+2(3.14)(8)(4)

2(3.14)(64)+2(3.14)(32)

2(200.96)+2(100.48)

401.92+200.96

602.88
