The area of each pizza and cost per inch is $12.82 per square inches and $11.304 per square inches respectively.

<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

Alekssandra [29.7K]

Answer:

180° - x = 5 · ( 90° - x )

180° - x = 450° - 5 x

5 x - x = 450° - 180°

4 x = 270°

x = 270° : 4

x = 67.5°

The measure of an angle is 67.5°.

Its complement angle: 22.5°.

Its supplement angle: 112.5°

112.5° = 5 x 22.5
