Question

A circle has a diameter of 6 inches.

What is the best approximation of its area?

Use 3.14 to approximate for π .
9.42 square inches
28.26 square inches
18.96 square inches
113.04 square inches

Answer 1

28.26 square inches

Explanation:

The diameter of the circle is 6 inches, so the radius is one-half of 6, or 3 inches.

`3.14( {3}^(2) ) = 3.14(9) = 28.26`

For your information, the exact area is 9π square inches, or approximately 28.274 square inches.
