The diameter of a bicycle wheel is 42cm. If the wheel makes 16 complete revolution, what will be the total distance covered by the wheel? [Take \(\pi \frac{22}{7}\)
A
672cm
B
1056cm
C
2112cm
D
4224cm
Verified Correct Answer: C.
Step-by-Step Mathematical Solution
d = 42cm
Circumference = \(\pi d = \frac{22}{7} \times 42cm\)
= 22 x 6cm = 132cm
Total distance covered = circumference x number of revolutions
= 132cm x 16 = 2112cm
