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
Correct Answer: Option C
Explanation
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
