A ground is in the form of a circle whose diameter is 350 m. An athlete makes 4 revolutions. Find the distance covered by the athlete

###### Advertisements

#### Solution

Diameter of the ground d = 350 m

Distance covered in 1 revolution = Circumference of the circle

= πd units

= `22/7 xx 350 "m"`

= 22 × 50

= 1100 m

Distance covered in 1 rotation = 1100 m

Distance covered in 4 revolutions = 1100 × 4

= 4400 m
