The size of a bicycle is determined by the diameter of the wheel. You want a 22-in bicycle for your birthday. What is the area of one of the wheels?

A = pi * r^2

A = 3.14 * 11^2

A = 3.14 * 121

A = 379.94 sq. in.

To calculate the area of one of the wheels of a bicycle, we need to know the diameter of the wheel. The diameter is the distance from one edge of the wheel to the other, passing through the center. In this case, the diameter of the wheel is given as 22 inches.

To find the area of a circle, we can use the formula A = πr², where A denotes the area and r represents the radius of the circle. The radius is half the diameter, which means r = 22/2 = 11 inches.

Now, we can substitute the value of the radius into the formula to find the area of the wheel:

A = πr²
A = π(11)²
A = π(121)
A ≈ 380.13 square inches.

Therefore, the area of one of the wheels is approximately 380.13 square inches.
