Question 13

A, B and C are the centres of three congruent circles. Each radius is 10 cm. Find the total shaded area, in cm², using π = 3.14.

Question illustration

Enter a number or exact fraction only.

Diagram convention: each centre lies on both other circles, so AB = BC = CA = 10 cm. Only the three pairwise-overlap lobes outside the central triple overlap are shaded. These relationships are implicit in the source drawing.
