The radius of a bicycle wheel is 14 cm. Find the distance covered by the wheel after making 50 complete rotations.

A. 44 meters
B. 88 meters
C. 132 meters
D. 176 meters

Answer :

Final answer:

To find the distance covered by the bicycle wheel after 50 rotations, calculate the wheel's circumference and multiply by the number of rotations. The total distance covered is 44 meters (option a).

Explanation:

The answer to the question involves calculating the circumference of the bicycle wheel and then multiplying it by the number of rotations to find the total distance covered. The radius of the bicycle wheel is given as 14 cm. First, we find the circumference (C) of the wheel using the formula C = 2 *
(pi) * radius. Plugging in the radius, C = 2 * 3.1416 * 14 cm = 87.9648 cm.

Next, to find the distance covered by 50 rotations, we multiply the circumference by the number of rotations:
Distance = Circumference * Number of Rotations = 87.9648 cm * 50 = 4398.24 cm.
Converting centimeters to meters, we have the distance covered as 43.9824 meters, which rounds off to 44 meters. Therefore, the correct option is A. 44 meters.
