Answer 1

Answer:

A copper wire when bent in the form of a square encloses an area of

484 cm?. The same wire is now bent in the form of a circle. Find the area

enclosed by the circle.

Answer 2

a^2= 484 i.e a=22 so the length of the copper wire would be 4a= 88cm
This will be the circumference of the circle
C= 2(pie)r
r= 88/2(Pie)
r= 14
Area of circle = (Pie)r^2
AOC = 22 * 14^2 / 7
AOC= 616
