Use the value 3.14 for a, and do not round your answer.
Be sure to include the correct unit in your answer.

Answer 1

Answer: 153.86

Explanation:

Area of circle = r^2*3.14

r=7

7^2*3.14= 153.86

Answer 2

153.86 squared inches

Explanation:

Area of a circle = pi r^2

Given pi = 3.14

Diameter = 14inches

r = radius

r = diameter/2

= 14/2

= 7 inches

Therefore area = 3.14 x (7)^2

= 3.14 x 7 x 7

3.14 x 49

153.86 squared inches
