If 4 circles of equal radius are drawn with vertices of a square as the centre , the side of the square being 7 cm, find the area of the circles outside the square ?

A) 119.21 sq cmB) 115.395 sq cmC) 104.214 sq cmD) 111.241 sq cm

Answer:   B) 115.395 sq cm 

Explanation:

Because each vertice of the square is the center of a circle
(1/4) part of the total area of each circle inside of the square.
(3/4) part of the total area of each circle outside of the square.
Thus total area outside the square is 4(34×227×3.5×3.5)434×227×3.5×3.5 = 115.3955 sq cm.
