The radius of the larger circle is 10cm. the radius of the smaller circle is 3cm. what is the approximate area of the shaded region?

The area of the shaded region would be given by the area of the larger circle - the area of the smaller circle:

Area of a circle = πr^2
Area of smaller circle = π*3^2 = 9π
Area of larger circle = π*10^2 = 100π

Area of shaded region = 100π - 9π
= 91π
Given that π is approximately equal to 3.14, the area of the shaded region would be approximately equal to 285.74 cm^2
