Question

clinton purchased a circular rug to cover part of a floor. The diameter of the rug is 8 feet. rounded to the nearest whole numbe, what area of the flooor will the rug cover?

Answer 1

Let’s change diameter into radius by just dividing it by 2. The radius is 4. Now, we need to square the radius. The radius squared would be 16. Let’s multiply 16 by pi to find the area.
16•pi
50.265
Rounded to the nearest whole number.
50
So it will cover 50 square feet.

Answer 2

the area of the rug will be 16π
