- Find the area of the full circle
- Find the area of the rectangle
- Find the difference (full circle area - rectangle area)
<h3><u>Step 1. Find the area of the full circle</u></h3>
Recall the formula for the area of a circle: 
where 
, and "r" is the radius of the circle (distance from center to any point on the edge).
From the diagram, the radius is 5cm.
![A_{circle}=(3.14)(5[cm])^2](https://tex.z-dn.net/?f=A_%7Bcircle%7D%3D%283.14%29%285%5Bcm%5D%29%5E2)
![A_{circle}=78.5[cm^2]](https://tex.z-dn.net/?f=A_%7Bcircle%7D%3D78.5%5Bcm%5E2%5D)
<h3><u>Step 2. Find the area of the rectangle</u></h3>
Recall the formula for the area of a rectangle: 
where "b" is the base of the rectangle (length of bottom or length of top), "h" is the height of the rectangle (distance from bottom to top).
From the diagram, the base is 8cm, and the height is 6cm.
![A_{rectangle}=(8[cm])(6[cm])](https://tex.z-dn.net/?f=A_%7Brectangle%7D%3D%288%5Bcm%5D%29%286%5Bcm%5D%29)
![A_{rectangle}=48[cm^2]](https://tex.z-dn.net/?f=A_%7Brectangle%7D%3D48%5Bcm%5E2%5D)
<u />
<h3><u>Step 3. Find the difference (full circle area - rectangle area)</u></h3>
Having found the areas for each of the first parts, we can find the difference to find the shaded area:
![A_{shaded}=(78.5[cm^2])-(48[cm^2])](https://tex.z-dn.net/?f=A_%7Bshaded%7D%3D%2878.5%5Bcm%5E2%5D%29-%2848%5Bcm%5E2%5D%29)
![A_{shaded}=30.5[cm^2]](https://tex.z-dn.net/?f=A_%7Bshaded%7D%3D30.5%5Bcm%5E2%5D)

Answer:
Please look at the image
From the info 2 jars with 106 sprinkles each, we know 1 jar would have 53 sprinkles.
1 jar has 53 sprinkles.
6 jars have 318 sprinkles because:
6 × 53 = 318
13 jars have 689 sprinkles because:
13 × 53 = 689
