Question

The distance traveled by a cyclist moving on a circle of radius 15m and make 3.5
revolutions will be (I revolution = 2π radian)
A. 26.25 m
B. 52.5 m
C. 105 m
D. 330 m
​

Answer 1

Answer:

GIVEN

We are given that a cyclist moves along a circle of radius 15 m and it is given that the cyclist makes 3.5 revolutions

TO FIND

We need to find the total distance covered by the cyclist

SOLUTION

R = 15m

No. of revolutions = 3.5

Total distance covered in one revolution = 2*pi*R

In one revolution, distance= 2*pi*15= 30pi m

Total distance covered in 3.5 revolutions= 3.5×30pi m

Total distance covered= 105pi

Total distance covered= 330m

ANSWER

The total distance covered in 3.5 revolutions is 330m
