The area of a circle is 615.44 in^2. What is the diameter of the circle? Use 3.14 for π.
To find the diameter of a circle when given the area, we can use the formula:
Area = π * (diameter/2)^2
Given that the area is 615.44 in^2 and using π = 3.14, we can plug these values into the formula and solve for the diameter:
615.44 = 3.14 * (d/2)^2
615.44 = 3.14 * (d/2) * (d/2)
615.44 = 3.14 * (d^2/4)
615.44 = 0.785d^2
784 = d^2
d ≈ √784
d ≈ 28
Therefore, the diameter of the circle is approximately 28 inches.
