Question

Rahul runs around the circular field once .Ravi runs across the field through the centre once.who runs more and how much.​

Answer 1

Answer:

We are given that Yamini had covered 1200 m

So, to find the radius

2\pi r = 1200\:m2πr=1200m

r = \frac{1200*7}{22*2}r=

22∗2

1200∗7

r = 190.90r=190.90

Now, to find the distance covered by Farah,

= 2*2r=2∗2r

= 2*2*190.90=2∗2∗190.90

= 763.6=763.6

From the above calculations we get that Yamini covered more distance as we were given 1200 m

and of farah we got 763.6 m

So subtracting distance of farah by yamini's

we get

=(1200-763.6)=(1200−763.6)

= 436.4\: m=436.4m

Therefore, Yamini ran more by 436.4 m

Answer 2

Step-by-step explanation:

Let the radius of circular field be 7 mtr.

Distance covered by Rahul when he run around the field = Circumference of circular field=2πr

=2×22/7 × 7 = 44 mtr,

Now,

Distance covered by Ravi when he run accross the centre of the circular field= Diameter=2r

=2×7=14 mtr,

Therefore we can say that Rahul runs more
