Question

The area of ​​a circular plain is 2464 air. How much wire lagega has to put four circles of wire around it
(1 air
= 100 sq m)
Will it take?​

Answer 1

Answer:

Hey there!

Given, Area of circle = 2464 meters.

We know that,

Area of circle = πr² .

We will first find out radius and then find circumference.

So,

➜πr²= 2464

➜ r² = 2464 * 7/22

➜r² = 784

➜ r = 28 m

Now, circumference of the circle = 2πr = 2 (22/7)(28) = 2(22)(4) = 88(2) = 176m .

Therefore, The circumference of the circle is 176 meters.

Correct option is 2
