Question

Use the π key to calculate the area of the circle below to the nearest hundredth. Which is the better estimate, 98 m2 or 99 m2?
98 m squared or 99 m squared question markExplain.

A circle has a radius measuring 5.6 meters.

Answer 1

The area of a circle is calculated by using the formula A = πr2. Therefore, the area of the circle is 98.53 m2. Since the question asks for the area to the nearest hundredth, the better estimate is 98 m2.
