Question

5. A farmer has 100 m of wire fencing. What area can she enclose if

Answer 1

First find the radius of the circle:

The formula for circumference = C = 2 x PI x radius

The circumference would be the length of the fence.

100 = 2 x 3.14 x radius

100=6.28 x radius

Radius = 100/6.28

Radius = 15.92

Area of a circle = PI x radius^2

Area = 3.14 x 15.92^2

Area = 795.82 square feet.
