Acylinder has a radius of 50 ft and a height of 18 ft. what is the exact surface area of the cylinder?

Answer

6800π ft²

Explanation

The surface area of a cylinder involves 2 parts.

1) the circular parts (bottom and the top)

2) the curved surface.

The area of the circular parts = 2×π×r²

= 2 × π × 50²

= 5000π ft²

The area of the curved surface = 2πrh

= 2 × π ×50 × 18

= 1800π ft²

The total surface area of the cylinder = 5000π+1800π

= 6800π ft²

I gave the answer in terms of pie (π) to avoid rounding which will make the answer an estimate.

The exact answer is 6800π ft².

1 is c
