A bicycle training wheel has a radius of 3 inches. The bicycle wheel has a radius of 10 inches. Approximately how much smaller, in square inches, is the areaof the training wheel than the area of the regular wheel?Use 3.14 for pi
The area of the training wheel can be calculated using the formula for the area of a circle: A = πr^2.
For the training wheel:
A_training = π * (3)^2
A_training ≈ 3.14 * 9
A_training ≈ 28.26 square inches
For the regular wheel:
A_regular = π * (10)^2
A_regular ≈ 3.14 * 100
A_regular ≈ 314 square inches
The difference in area between the regular wheel and the training wheel is:
Difference = A_regular - A_training
Difference = 314 - 28.26
Difference ≈ 285.74 square inches
Therefore, the training wheel is approximately 285.74 square inches smaller than the regular wheel.
