Question

The radius of a circular field is 24.5 find the ditance run by a boy in making 4 complete rounds

Answer 1

Answer:

308

Step-by-step explanation:

circumference formula=2*pi*r

2*22/7*24.5*2

Answer 2

Given that : The radius of circular field = 24.5 m

As we know that : Circumference of Circle = 2πr , where r = radius of Circle.

Now, according to the question :

One round of circular field :

$2 \times \frac{22}{7} \times 24.5 \\ \\ = > 154 \: m \:$

Then, distance of 4 rounds :

$4 \times 154 = 616 \: m$
