Question

Calculate total distance covered by an athlete in completing one round of a circular track of radius 7 m . *

88 m

44 m

32 m

22 m

Answer 1

Answer:

44 m

Explanation:

Given :

The radius of the circular track is 7 cm

To find :

the total distance covered by an athlete in completing one round of circular track.

Solution :

The radius of the circular track is 7 m

r = 7 m

The distance covered by the athlete round the circular track once is equal to the circumference of the circle.

Circumference of the circle is given by,

⇒ C = 2πr

where

π = 22/7

r denotes the radius of the circle

Let's find the circumference of the circular track.

Circumference of the circular track :

C = 2πr

C = 2 × 22/7 × 7

C = 2 × 22

C = 44 m

Circumference of the circular track = 44 m

Therefore, the total distance covered by the athlete in completing one round of circular track is 44 m
