Answer:
First, find the circumference of the wheel. Circumference is the distance around the circle, so it's the same distance the wheel travels in one rotation. Since the diameter is the distance across the circle, the circumference is equal to π times the diameter. Plugging in the diameter of 0.7 meters and using 3.14 for π, we get a circumference of 0.7π≈2.195 meters.
We now divide the total distance traveled, 76 meters, by the circumference to find the number of rotations. 76 meters÷2.195 meters per rotation≈34.6 rotations.
Since the wheel cannot make part of a rotation, we round 34.6 up to 35. Over the 76 meter race, the wheel rotates 35 times.
