A bicycle training wheel has a radius of 3 inches a regular bicycle wheel has a radius of 10 inches approximately how much smaller and square inches and rounded to the nearest hundredth is the area of the training wheel than the area of the regular bicycle wheel
The area of a circle is calculated using the formula A = πr^2, where A is the area and r is the radius.
For the training wheel:
Radius = 3 inches
Area = π(3)^2 ≈ 28.27 square inches
For the regular bicycle wheel:
Radius = 10 inches
Area = π(10)^2 ≈ 314.16 square inches
The difference in area between the two wheels is:
314.16 - 28.27 ≈ 285.89 square inches
Therefore, the area of the training wheel is approximately 285.89 square inches smaller than the area of the regular bicycle wheel.
