62.8 square inches
1,256 square inches
314 square inches
15.7 square inches
The area of a circle is given by the formula A = πr^2, where r is the radius of the circle. Since the diameter of the bicycle wheel is 20 in, the radius is half of the diameter, so the radius is 20/2 = 10 in.
Plugging the radius into the formula, we get:
A = 3.14 * 10^2
A = 3.14 * 100
A = 314 square inches
Therefore, the area of the wheel is 314 square inches.
