Question

Work out the surface area of this cylinder. 8 cm 16.8 cm​

Answer 1

The complete question is

" Work out the surface area of this cylinder if the diameter of the cylinder is 8 cm and height is 16.8 cm."

The surface area of the cylinder of diameter 8 cm and height 16.8 cm would be 547.616 cm sq.

What is the surface area of the cylinder?

The surface area of the cylinder of the radius of the base r and the height h,

A = 2πr ( r + h)

We have been given as

diameter = 8 cm

Height = 16.8cm

The radius = 8/2 = 4cm

The surface area of the cylinder

A = 2πr ( r + h)

A = 2 x 3.14 x 4 ( 4 + 16.8)

A = 25.12 (21.8)

A = 547.616 cm sq.

Hence, The surface area of the cylinder of diameter 8 cm and height 16.8 cm would be 547.616 cm sq.
