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

Answer 1

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.
