Number 4 help please!! thank you!

We know that the area of a circle = 3.14*r^2

r = radius.

First let's find the area of the circles in white.

The area of the small circle = 3.14 * 4^2 = 50.2 cm^2

The area of the larger white circle = 3.14 * 8^2 = 201cm^2

The total area of the non-shaded region = 251.2 cm^2

Now, let's find the area of the giant circle.

The diameter = 24 cm so that means the radius = 12 cm

A = 3.14 * 12^2 = 452.2 cm^2

Now subtract the white circles from the giant circle.

452.2 - 251.2 = 201cm^2

The area of the shaded region = 201cm^2

idk lol xd
