Question

A wire of length 484m is bent in the shape of a circle. Find the area of the circle

Answer 1

Step-by-step explanation:

the lenght of the wire = perimeter of circle

perimeter= 2πr

484= 2πr

484*7/2*22=r

3388/44=r

77=r

area = πr^2

22/7*77^2

22/7*5929

22*847

18634 m^2

Answer 2

Given: wire length 484 m

To find: area of circle

Step-by-step explanation:

In Latin word circumference is total distance around of a circle carrying it.It is made up many such point arranged equal distance from single mid point and the point is called as the center of the circle.

According to question

circumference of circle = length of the wire

$2\pi r=484$

$r=\frac{480\times 7}{2\times22}$

$r=\frac{3360}{44}$

$r=77cm$

Area of circle = $\pi r^2$

                       = $\frac{22}{7} \times77\times 77$

                       = $22 \times 11 \times 77$

                       =$18634m^2$
