Answer:

step by step

Step-by-step explanation:

where

r = radius

h= height

Area of a cylinder = 2πrh+2πr^2

Area of a cylinder = 2π8(3)+2π8^2

Area of a cylinder = 176π = 552.92

Area of a hemisphere= 3r2π

Area of a hemisphere= 3(2)2π

Area of a hemisphere= 12π = 37.699111843

Area of the cylinder in this problem

176π - 12π = 164π
