Question

What is the surface area of the cylinder?

A.) 96π ft^2
B.) 112π ft^2
C.) 80π ft^2
D.) 88π ft^2

Answer 1

i think it is C 80π ft^2

that is because 10*8=80

Answer 2

B = 112πft^2

Explanation:

Surface area of cylinder= 2πrh+2πr^2

Radius r = 8ft/2 = 4ft

Height h = 10ft

2×π×4×10 + 2×π×4×4

80π + 32π = 112πft^2
