The lid for a circular plastic food container has a diameter of 9 cm.What is the approximate area of the top of the lid? Use 3.14 to approximate pi and round your answer to the nearest hundredth.


_____cm2

Answers

Answer 1
Answer: If the diameter is 9 cm the radius is 4.5 cm (half the diameter).  The area of a circle is given by the formula:  4πr^2, where π is the constant ratio of circumference to diameter (3.14159...).

3.14 cm x 4.5 cm = 14.13 cm^2.  Remember, the units must be squared to represent area.  14.13 is extended to the nearest hundredth.
