The area of a circle is increasing at a constant rate of 118 square feet per minute. At the instant when the area of the circle is 25\pi25π square feet, what is the rate of change of the radius? Round your answer to three decimal places.

what

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

the answer is 13 cm

i think the answer is d im not sure
