There are 10 rings on an archery target. Each ring is 4 cm wide.

Find the area of:

1. the yellow region (rings 9 and 10)
2. the red region (rings 7 and 8)
3. the black region (rings 3 and 4)

A circle with a 12-inch diameter is folded in half and then folded in half again. What is the area of the resulting shape?

Some Hawaiian chiefs wore capes that were covered with red, yellow, and black feathers.

Describe how you could estimate the area of this cape.

Find the area of the shaded region. Express your answer in terms of \(\pi\).

A shaded rectangle with three unshaded circles stacked one above the other inside the rectangle. The horizontal length of the rectangle is 18 inches. On the right side of the rectangle, the length of the vertical side is subdivied into 4 different lengths using arrows. The first arrow indicates that the distance from the top of the rectangle to the top of the first circle is 3 inches. The second arrow indicates that the distance from the top to the bottom of the first circle is 6 inches. The third arrow indicates that the distance from the top to the bottom of the second circle is 9 inches. The fourth arrow indicates that the distance between the top to the bottom of the third circle is 12 inches.

Find the area of this shape in two different ways.

Elena and Jada both read at a constant rate, but Elena reads more slowly. For every 4 pages that Elena can read, Jada can read 5.

1. Complete the table.

   pages read by Elena	pages read by Jada
   4	5
   1
   9
   \(e\)
   	15
   	\(j\)

2. Here is an equation for the table: \(j = 1.25e\). What does the 1.25 mean?
3. Write an equation for this relationship that starts \(e = \text{...}\)
