Short Answer 
The diameter of the bicycle wheel is 63 centimeters, and it covers 198 centimeters in one full rotation. By applying the formula for circumference (C = π * d), we find that π can be approximated as 7/22.
Step 1: Identify the Wheel’s Dimensions
To begin with, determine the diameter of the bicycle wheel. In this case, it is given as 63 centimeters. This information is crucial as it will be used to calculate the circumference of the wheel.
Step 2: Understand Wheel Circumference
Next, we will look at the circumference of the wheel, which represents the distance the bicycle travels in one full rotation. According to the information provided, the wheel covers 198 centimeters when it completes one full rotation.
Step 3: Relate Diameter to Circumference using π
Finally, we will use the formula for circumference, which is π multiplied by the diameter (C = π * d). Plugging in the values, we get π * 63 = 198. To solve for π, rearrange the equation resulting in π = 198 / 63, leading to π being approximately 7/22.
