<h3>How to solve area of a circle?</h3>
Large:
Diameter = 14 inches
Radius, r = 14 / 2
= 7 inches
Area = πr²
= 3.14 × 7²
= 3.14 × 49
= 153.86 square inches
Cost per inch = 153.86 square inches / 12
= 12.8216666666666
Approximately, $12.82 per square inches
Medium:
Diameter = 12 inches
Radius, r = 12/2
= 6 inches
Area = πr²
= 3.14 × 6²
= 3.14 × 36
= 113.04 square inches
Cost per inch = 113.04 square inches / 10
= $11.304 per square inches
