Q.

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 ?

View Answer

Correct choice: B

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(3/4×22/7×3.5×3.5) = 115.3955 sq cm.
