To find the diameter of the circle, we can use the formula for the area of a circle:
A = πr^2
615.44 = 3.14 * r^2
615.44 / 3.14 = r^2
r^2 = 196
Now, find the square root of 196 to get the radius:
r = √196
r = 14
The diameter of a circle is twice the radius, so:
d = 2 * 14
d = 28
Therefore, the diameter of the circle is 28 inches.
The correct answer is E) 28 in
