Question

A 264 CM LONG THIN WIRE IS BENT IN THE FORM OF A CIRCLE AND KEPT ON THE GROUND .FIND THE AREA OF THE GROUND ENCLOSED BY THE WIRE................................... it's answer is-5544 cm square

Answer 1

If the length of the wire is equal to the circumference of circle. So we can yse the formula of circumference of circle.. which is = 2 pi r
So.. 2 pi r = 264
=> r = 264 × 7/22 × 1/2
= 42
So the radius of circle is 42 cm
So the area of circle = pi r^2
= 22/7 × 42^2
= 22× 6 × 42 = 132 × 42
= 5544 cm sqr
