The wheel turns 26.69 inches in one revolution.
Explanation:When it asks, "how many inches does the wheel turn in one revolution," it is asking for the circle's circumference. The formula for circumference is pi x diameter (3.14 x 8.5). So we would multiply 3.14 x 8.5, which we get 26.69. Therefore, the wheel turns 26.69 inches in one revolution
