1 revolution = 2 × 22/7 × 35/2 = 110cm
110 = 1.1 m
200 revolution = 1.1 × 200= 220m
1 min → 220m
1/6 hr(10min) → 2200m
110 = 1.1 m
200 revolution = 1.1 × 200= 220m
1 min → 220m
1/6 hr(10min) → 2200m

Answer is 2200m because the circumference of a circle is 2(pi)r, so you’ll need to divide 35cm by 2 to find the radius
