Step-by-Step Solution
Step 1: Convert distance to centimeters
First, we need to convert the total distance covered from kilometers to centimeters to ensure consistent units throughout the calculation. We know that 1 kilometer is equal to 1000 meters, and 1 meter is equal to 100 centimeters.
Step 2: Calculate total distance in centimeters
Multiplying the conversion factors, we find that 11 kilometers is equivalent to 1,100,000 centimeters.
Step 3: Calculate distance covered in one revolution
The distance covered in one revolution of the wheel is equal to its circumference. We can find this by dividing the total distance covered by the total number of revolutions.
Step 4: Simplify distance per revolution
Performing the division, we find that the wheel covers 220 centimeters in one complete revolution.
Step 5: Calculate the diameter
The distance covered in one revolution is the circumference of the wheel, which is given by the formula C=πd, where d is the diameter. We can use the approximation π=722 to find the diameter.
Step 6: Solve for diameter
By substituting the circumference and the value of π, we calculate the diameter of the wheel to be 70 centimeters.
