Question

Using 3.14 as an approximation of pi, how do you find the distance to the outside edge of a wheel with a 30 millimeter diameter?

A. 3.14 mm
B. 60 mm
C. 94.2 mm
D. 15.7 mm

Answer 1

To find the distance to the outside edge of a wheel with a 30 millimeter diameter using the approximation of pi as 3.14, calculate the circumference of the wheel using the formula C = 2πr. The correct answer is C, which is 94.2 millimeters.

Step-by-step explanation:

To find the distance to the outside edge of a wheel with a 30 millimeter diameter using the approximation of pi as 3.14, you need to calculate the circumference of the wheel. The circumference of a circle can be found using the formula C = 2πr, where r is the radius of the circle. In this case, the radius of the wheel is half of the diameter, so it is 15 millimeters. Plugging in the values, we get C = 2 * 3.14 * 15 = 94.2 millimeters.

Therefore, the correct answer is C. The distance to the outside edge of the wheel is 94.2 millimeters.

Answer 2

To find the distance to the outside edge of a 30 millimeter diameter wheel using 3.14 as pi, calculate the circumference with the formula C = πd, giving C = 3.14 × 30 mm = 94.2 mm. The correct answer is C. 94.2 mm.

Step-by-step explanation:

To find the distance to the outside edge of a wheel with a 30 millimeter diameter using 3.14 as an approximation of pi, you would calculate the wheel's circumference since the distance to the outside edge refers to the circumference of the wheel. The formula for the circumference (C) is C = πd, where π is pi and d is the diameter of the wheel. Substituting 3.14 for pi (π) and 30 mm for the diameter (d), the calculation would be:

C = 3.14 × 30 mm = 94.2 mm

Therefore, the correct answer is C. 94.2 mm, which is the distance to the outside edge of the wheel.
