Question

Cupertino Middle School is painting a circle on their playground with a radius of 4 feet. What will be the total area of the circle, in square feet? Use n = 3.14, and round your answer to the nearest hundredth.

Answer 1

The area A of a circle with radius r is given by the following formula:

`A\text{ = }\pi r^2`

in this case, r = 4, so the area of the given circle would be:

`A\text{ = }\pi r^2=\text{ }\pi(4)^2=50.24`

so that, the correct answer is:

`50.24`
