First, we use the formula for the area of a circle:
A = πr^2
Given that the area is 615.44 in^2, we can plug that in and solve for the radius:
615.44 = 3.14r^2
615.44 / 3.14 = r^2
196 = r^2
r = √196
r = 14
Now that we have the radius, we can find the diameter by multiplying the radius by 2:
D = 2r
D = 2 * 14
D = 28
Therefore, the diameter of the circle is 28 inches.
The area of a circle is 615.44 in 2
. What is the diameter of the circle? Use 3.14 for π.
