Question

! Find the area of a circle made of 1m wire ?
​

Answer 1

Answer:

Here's Your Answer

Step-by-step explanation:

◆It's really simple if you play around with area of a circle's equation.

The area of a circle is given by the formula A = π r², where A is the area and r is the radius. Since we know the circumference of a circle is give by C =2 π r.

If we play around with 'r' in the second equation, then we get r= C/2π. Now if we substitute new value found for 'r' in the first equation, the we get A= π [C/(2π)]²

Simplyfying the equation, we get A= C²/ 4π

Now if we put the value of C in the above equation, you'll get the value of area of the circle. Just keep in mind that you should substitute π with 3.14
