The diameter of a bicycle wheel is 20 in. What is the area of the wheel? (Use 3.14 for π)
First, we need to find the radius of the wheel by dividing the diameter by 2.
Radius = 20 in / 2 = 10 in
Next, we can calculate the area of the wheel using the formula for the area of a circle:
Area = π * r^2
Area = 3.14 * (10 in)^2
Area = 3.14 * 100 in^2
Area = 314 in^2
Therefore, the area of the bicycle wheel is 314 square inches.
