A square fence encloses a circle. Calculate the area of the circle in m2 if the area of the square is 800 m2. The area of a circle is Pi x r2. Pi can be taken as 22/7.

Answer»

Step-by-step EXPLANATION:

AREA of square=a²

800=a²

a=20√2

radius of a circle=half the SIDE of a square

r=20√2/2

r=10√2

area of circle=πr²

a=22/7*(10√2)²

a=628.57m²
