A 14 in
To find the diameter from the area of a circle, use the formula: A = πr^2.
Given that the area of the circle is 615.44 in^2 and π = 3.14, you can find the radius by rearranging the formula:
615.44 = 3.14r^2
615.44 / 3.14 = r^2
196 = r^2
r = √196
r = 14 in
The diameter is twice the radius, so:
Diameter = 2r
Diameter = 2(14)
Diameter = 28 in
Therefore, the diameter of the circle is 28 in.
The area of a circle is 615.44 in 2 . What is the diameter of the circle? Use 3.14 for π.

you sure
I apologize for the error in my calculation. Let me redo the calculation:
Given the area of the circle is 615.44 in^2 and using the formula of the area of a circle (A = πr^2), we have:
615.44 = 3.14 * r^2
r^2 = 615.44 / 3.14
r = sqrt(196) = 14
So, the radius of the circle is 14 in.
The diameter of the circle is twice the radius, so the diameter = 2 * radius = 2 * 14 = 28 in.
Therefore, the correct diameter of the circle is 28 in. Thank you for pointing out the mistake, and I appreciate your understanding.
