Answer:

C) 302 ft².

Step-by-step explanation:

Given :  A circle with radius 14 ft and a circle with radius 10ft.

To find : what is the difference in the areas.

Solution : We have given that  radius 14 ft and a circle with radius 10ft.

Area of circle = π(radius)^{2}

Area of circle 1 =  π(14)^{2}

Area of circle 1 = 196 * 3.14.

Area of circle 1 = 615.44 ft².

Area of second 2 =  π(10)^{2}

Area of circle 2 = 100 *3.14.

Area of circle 2 = 314 ft²

Difference  =  615.44 - 314

Difference  = 301.44  ft²

Rounded 302 ft²

Therefore, C) 302 ft².
