The area of the shaded region is 39.3.
Given the diagram shows a circle inside a semicircle.
Every point in the plane of a circle, which is a closed, two-dimensional object, is evenly separated from the center. All lines that cross the circle join together to produce the line of reflection symmetry. Every angle also possesses rotational symmetry about its center.
Area of a circle = .
Semicircle is when a line travelling through the center of a circle reaches its two ends, a semicircle is created. Thus, a circle can be formed by combining two semicircles.
Area of a semicircle = .
The circle has a diameter of 10 cm. The semicircle has a diameter of 20 cm.
Semicircle:
Circle:
So,
Therefore, The area of the shaded region is 39.3.
