A wire in the shape of a square of side 11m is rebent intothe shape of a circle.Find the area of the circle?
Answer
154 square metres.
Steps
Perimeter of the square is 4x11 metres.
44 metres.
The perimeter of the circle will be the same.
2x(pi)xR eq 44
R eq. (44)/(2x(pi))
44/(2x(22/7)
Eq (44x7)/(2x22)
7 metres
Area of cirlcle eq
(Pi)x(R**2)
(22/7)x(7x7)
154 sq metres
