Question

What is the surface area of a cylinder with a radius of 8 and a height of 16?

*NOTE: Answer must NOT be decimal or fraction.*

Answer 1

The surface area of the cylinder is A= 1206.37

Answer 2

Lateral surface area
=2πrh
=2π(8)(16)
=256π
End areas
=2πr²
=2π(8²)
=128π
Total surface area
=lateral area+end areas
=256π+128π
=384π
