The area of the circular shaded area is of 116.113 cm².
What is the area of a circle?
The area of a circle of radius r is given by pi multiplied by the radius squared, as follows:
A = πr²
For this problem, the shaded area is the area of the larger circle subtracted by the area of the smaller circle. We have that:
- The radius of the larger circle is of 6.5 cm.
- The radius of the smaller circle is of 2.3 cm.
Hence the area of the larger circle is given by:
Al = π(6.5)² = 132.732 cm².
The area of the smaller circle is given by:
As = π(2.3)² = 16.619 cm².
Hence the shaded area is given by:
A = Al - As = 132.732 - 16.619 = 116.113.
The shaded area is of 116.113 cm².
