Her sponsors agreed to donate an amount of money for each mile she walked. How many miles did she walk? First, fill in the blanks on the left side of the equation using three of the ratios shown. Then write your answer on the right side of the equation.
Ratios: 3ft/1yd 1yd/3ft 5280ft/1mi 1mi/5280ft 1600yd/1lap 1lap/1600yd

37.69    (≈ 38 ft²)

Step-by-step explanation:

2πr = 30.77

r = 30.77 / (2 * 3.14) = 4.9

half of free-throw circle area: πr² / 2 = (3.14 * 4.9²) / 2 = 37.69    (≈ 38 ft²)
