Answer:

Explanation: The diameter of the circle is 28 inches.

Given:

Area of a circle = 615.44 in²

Area of a circle is computed by multiplying pi and the radius raised to the 2nd power.

A = π r²

615.44 in² = 3.14 * r²

615.44 in² / 3.14 = r²

196 = r²

√196 = √r²

14 in = r

Diameter is twice its radius. So, d = 2r; d = 2 * 14 ; d = 28 inches
