Question 10
Find the total shaded area in the figure, in cm². Each circle has radius 20 cm. Use π = 3.14.
The source leaves some arc construction implicit. Use its intended symmetric construction: each lens is bounded by equal 90° arcs of radius 20 cm, and the four arc endpoints in each main circle form an inscribed square.
