Question

In square ABCD, there are shaded regions bounded by arcs of circles with centers at A,B,C and D. Determine the area of the white region.

A. 9
B. 36-3 π
C. 36-6 π
D. 36-9 π

Answer 1

Area of the square = 36

We can assume that the total area of the 4 circle sections is equal to the area of one circle with a 3 inch radius.

Area of Circle = PI * 3 * 3

Area of white region = 36 - PI * 9

Answer is D
