Question

The area of a circular mouse pad is 64 square inches. Use 3.14 for 7. Estimate its radius to the nearest integer.

Answer 1

about 4.52

Explanation:

Since pi times radius squared is the formula for area, you would first divide 64 by 3.14 to get about 20.4. Then since you square the radius, you would do the opposite and find the square root which is about 4.52.
