Question

The ball on the string makes a circular pattern 7 feet from the pole about how many square feet does the ball and strength swing use the fraction for pi

Answer 1

`A=49\pi\ ft^2`

Explanation:

Area Of A Circle

A circle with radius r has an area which can be computed by

`A=\pi r^2`

We have a ball on one string making a circular pattern 7 feet from the pole, i.e. its radius is 7 feet. The area covered by the pattern is

`A=\pi 7^2`

`\boxed{A=49\pi\ ft^2}`
