Question

A circular bicycle reflector has a diameter of 5 cm. What is the approximate area of the reflector? Use 3.14 to approximate pi and round your answer to the nearest hundredth. cm2

Answer 1

Explanation:

Area=pi×radius^2 so if diameter is 5 then radius is half that which is 2.5. So it should be a=3.14 × 2.5^2. I hope that's right.
