Question

A circle has a diameter of 28 inches. What is its area (to the nearest whole

number)? Let root square = 3.14.

Answer 1

616 in²

Explanation:

A= πr²

diameter = 28, so radius is half, so 14

π(14)² = 615.7 in² (616)

Answer 2

615 inch²

Explanation:

area of circle is π * radius * radius

radius is 28/2 = 14 inches

therefore area of circle is 3.14 * 14 * 14 = 615.44 inch²
