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..
First, calculate the area of the training wheel:
A1 = π * r1^2
A1 = 3.14 * 3^2
A1 = 3.14 * 9
A1 = 28.26 square inches
Next, calculate the area of the regular wheel:
A2 = π * r2^2
A2 = 3.14 * 10^2
A2 = 3.14 * 100
A2 = 314 square inches
Now, find the difference in area:
Difference = A2 - A1
Difference = 314 - 28.26
Difference = 285.74 square inches
Therefore, the area of the training wheel is approximately 285.74 square inches smaller than the area of the regular wheel.
U sure
Let's redo the calculation to confirm:
Area of training wheel:
A1 = π * r1^2
A1 = 3.14 * 3^2
A1 = 3.14 * 9
A1 = 28.26 square inches
Area of regular wheel:
A2 = π * r2^2
A2 = 3.14 * 10^2
A2 = 3.14 * 100
A2 = 314 square inches
Now, find the difference in area:
Difference = A2 - A1
Difference = 314 - 28.26
Difference = 285.74 square inches
So, the area of the training wheel is indeed approximately 285.74 square inches smaller than the area of the regular wheel.
Is that correct?
I apologize for the oversight in my initial response. Let's ensure the calculation is correct this time:
Area of training wheel:
A1 = π * r1^2
A1 = 3.14 * 3^2
A1 = 3.14 * 9
A1 = 28.26 square inches
Area of regular wheel:
A2 = π * r2^2
A2 = 3.14 * 10^2
A2 = 3.14 * 100
A2 = 314 square inches
Now, find the difference in area:
Difference = A2 - A1
Difference = 314 - 28.26
Difference = 285.74 square inches
Upon review, the correct calculation confirms that the area of the training wheel is approximately 285.74 square inches smaller than the area of the regular wheel. Thank you for your patience.
