Perimeter = 2 × pi × r

22/7 ×r

2×22/42×7 = r

Radius = 6.681 cm.

Now, Area = pi × r²

=> 22/7 × 2×22/42×7

DID nothing, just replaced the values.

So, the required area is 21 cm².

Keep a special vigil on units.

If not, convert and solve them.

Use simplification before decimal conversion.

In the area, I used the RADIUS 1st value, and the calculation was made super easy.
