how many times a wheel of radius 28cm must rotate to go 352 m?
answer = circumference of circle =
2×pie×r
2×22/7×28
176cm
distance to be covered = 352m
1m=100cm
352m=35200cm
35200/176=200

Answer:
200
Step-by-step explanation:
circumference of the circle= 2 x pi xr
= 2 x 22/7 x 28
= 176cm
distance to be covered = 352m
1m = 100cm
therefore,
352 x 100 = 35200cm
number of rotations = 35200/176
= 200
