The diameter of a bicycle wheel is 20 in. What is the area of the wheel? Use 3.14 for π) A=πr2
First, we need to find the radius of the wheel. Since the diameter is given as 20 inches, the radius will be half of that:
Radius (r) = Diameter / 2
r = 20 in / 2
r = 10 in
Now, we can use the formula for the area of a circle to calculate the area of the wheel:
A = πr^2
A = 3.14 * 10^2
A = 3.14 * 100
A = 314 in^2
Therefore, the area of the wheel is 314 square inches.
