The formula for the area of a circle is A = πr^2, where r is the radius of the circle.
For the training wheel:
Radius = 3 inches
Area = π(3)^2 = 9π ≈ 28.27 square inches
For the regular bicycle wheel:
Radius = 10 inches
Area = π(10)^2 = 100π ≈ 314.16 square inches
The difference in area 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.
A bicycle training wheel has a radius of 3 inches. A regular bicycle wheel has a radius of 10 inches. Approximately how much smaller, in square inches and rounded to the nearest hundredth, is the area of the training wheel than the area of the regular bicycle wheel
5 answers
that is wrong
Let's correct the calculation:
Training wheel:
Radius = 3 inches
Area = π(3)^2 = 9π ≈ 28.27 square inches
Regular bicycle wheel:
Radius = 10 inches
Area = π(10)^2 = 100π ≈ 314.16 square inches
The difference in area 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.
Training wheel:
Radius = 3 inches
Area = π(3)^2 = 9π ≈ 28.27 square inches
Regular bicycle wheel:
Radius = 10 inches
Area = π(10)^2 = 100π ≈ 314.16 square inches
The difference in area 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.
nope still wrong
Apologies for the error. Let's recalculate the difference in area between the two wheels:
Training wheel:
Radius = 3 inches
Area = π(3)^2 = 9π ≈ 28.27 square inches
Regular bicycle wheel:
Radius = 10 inches
Area = π(10)^2 = 100π ≈ 314.16 square inches
The difference in area 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.
Training wheel:
Radius = 3 inches
Area = π(3)^2 = 9π ≈ 28.27 square inches
Regular bicycle wheel:
Radius = 10 inches
Area = π(10)^2 = 100π ≈ 314.16 square inches
The difference in area 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.
