A circle is a curve sketched out by a point moving in a plane. The area of the shaded region is equal to 141.37 cm²
What is a circle?
A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.
The area of the shaded region can be found by subtracting the area of the larger circle from the area of the smaller circle. Therefore, the area of the shaded region is,
Area = π(9 cm)² - π(6 cm)²
= 141.37 cm²
