Question

an athlete runs on a circular track of radius 49m and cover a distance of 3080m along its boundary .How many round has he taken to cover this distance

Answer 1

circumference=2πr
so r=49
one round of the circle =to the circumference
so
2×22/7*4 9
= 2*22*7
=44* 7
=308
so no of rounds made
=3080/308
=10(ans)

Answer 2

The athlete takes 10 rounds to cover the distance.

• The radius of the circular track is 49m.

• Distance covered by the athlete on a circular track is 3080m.
• Distance covered by the athlete in one round = Circumference of the circular ground.

• Circumference of the ground = 2πr = 2×π×49 = 308 m.

• Now the athlete covers a total distance of 3080 m.

• We have to find the number of rounds that the athlete covers,

Number of rounds = $\frac{Distance \ covered \ by \ the \ athlete}{Circumference \ of \ the \ circle}$

• Number of rounds = $\frac{3080}{308}$ = 10

• The athlete takes 10 rounds to cover the distance.
