Find out the approximate diameter of the pond if sita once a distance of 1 km 980 m while while walking 15 times around the circular pond?

To find the diameter of the pond, we first need to find the circumference of the pond.

Given that Sita walked a distance of 1 km 980 m while walking 15 times around the pond, we can calculate the total distance she walked around the pond:

Total distance = 1 km 980 m * 15 = 29 km 700 m

Now, we know that the circumference of a circle is given by the formula:

Circumference = π * diameter

We can rearrange this formula to solve for the diameter:

Diameter = Circumference / π

Given that Sita walked a total distance of 29 km 700 m around the pond, we can calculate the circumference:

Circumference = 29 km 700 m

Now, we can calculate the diameter of the pond:

Diameter = 29 km 700 m / π
Diameter ≈ 9.42 km

Therefore, the approximate diameter of the pond is 9.42 km.

Distance covered by Sita in 15 rounds = 1 km 980 m = 1980 m

Let the diameter of the circular pond be 'd' meters.

Circumference of the circular pond = πd

Distance covered by Sita in 1 round = πd

Therefore, distance covered by Sita in 15 rounds = 15πd

So, 15πd = 1980

⇒ d = 1980/15π

⇒ d = 1980 × 7/15 × 22

⇒ d = 42 m

Hence, the approximate diameter of the pond is 42 meters.
