the images that are provided are of a rectangle circumscribed around a circle, and a rectangle inscribed within a circle.

1. what is the area of the smallest rectangle the can be circumscribed around the unit circle?

2. what is the area of the largest rectangle that can be inscribed within the unit circle?

3. approximate the area of the unit circle using an appropriate number of circumscribed rectangles if width 0.4 units.

4. approximate the area of the unit circle using an appropriate number of inscribed rectangles if width 0.4 units.

How would I go about setting this up. I am fairly lost.

Picture: View image: problem

There are more problems than are pictured, so I figure if I can find out how to do these first four, I can complete the rest. I will be posting my work as I finish it in order to confirm that I am doing everything correctly.
