Question

a circular mirror is surrounded by a square metal frame. the radius of the mirror is 4x. the side length of the metal frame is 20x. what is the area of the metal frame

Answer 1

Answer:

400x^2-16x^2pi

Step-by-step explanation:

To first start off, we need to find the area of the circle mirror. This is 16x^2pi.

Now, we need to find the area of the square, which results in 400x^2.

From here, we can subtract the circle from the square.

Because you cant subtract pi, we can leave it as it is.
