Answer:

C = 28.048

Step-by-step explanation:

Circumference = 2pi(r)

Area = pi(r)^2

62.6 = pi(r)^2

r^2 = 62.6/pi

r^2 = 19.926

r = 4.464

Therefore, circumference = 2pi(4.464)

= 28.048

Answer: 28.3 inches

Step-by-step explanation:

In order to find the circumference of the circle , we need to find the radius of the circle from the area given.

The formula for calculating area of circle is given by :

A = [tex]\pi r^{2}[/tex] , that is

63.6 = [tex]3.14[/tex] x [tex]r^{2}[/tex]

[tex]r^{2} = 63.6 / 3.14[/tex]

[tex]r^{2} = 20.25477707[/tex]

[tex]r = 4.5[/tex]

Therefore : to calculate the circumference of the circle , we will use the formula for calculating the circumference of a circle , which is

C = [tex]2\pi r[/tex]

C = [tex]2(3.14)(4.5)[/tex]

C = 28.26

C≈ 28.3 inches
