A circle with radius of 4 cm sits inside a circle with radius of 11 cm.
What is the area of the shaded region?
Round your final answer to the nearest hundredth.

The area of the shaded region = 330 sq cm

Step-by-step explanation:

Given,

The radius of small circle (r) = 4 cm

The radius of large circle (R) = 11 cm

To find the shaded region

Formula

The area of circle of radius r = π sq cm

So, The radius of the small circle = π× sq cm = 16π sq cm

The radius of the large circle = π× sq cm = 121π sq cm

Hence the area of the shaded region = 121π-16π sq cm

= 105π sq cm

= 105 × sq cm = 330 sq cm

answer is:

1.75 pounds
