Question 13

Find the area of the (gray) shaded region. (2 tangent circles inscribed in a rectangle):
20

Answer 1

42.92 square

Explanation:

The radius of the circles is 5m

So, area of 1 circle is π(5×5)=78.54 square

Two areas will (78.54+78.54)=157.08 square

Rectangles height is ( 5+5)=10m

Rectangles area is (10×20)=200 square

Shaded region=(200-157.08) square =42.92 square
