Question

1. A ground is in the form of a circle whose diameter is
420 m. An athlete makes 5 revolutions. Find the
distance covered by the athlete.​

Answer 1

Answer:

4200 m

explanation

first we need to find the length of its circumference,

we know diameter divides the circle into 2 equal halves.

circumference = diameter × 2

= 420×2 = 840m

distance covered by the athlete = circumference × 2. =840×5

=4,200m

so , the athlete covered a distance of 4,200 metres.
