Question

A circular picture is 8 inches in diameter.
What is the area of the picture in square inches

Answer 1

A≈50.27in²dDiameter8in

Answer 2

The area of a circle can be found by doing πr squared (Ugh phones don't have the fancy symbols)

So the radius, in this case, would be 8/2, or 4. So just do π * 4 ^ 2, or π * 16.

Assuming you use 3.14 for π, the area would be 50.24 inches squared.
