The area of the track will be 78501 m². The area of the track is equal to the area of the circle.

<h3>What is the area?</h3>

The space filled by a flat form or the surface of an item is known as the area.

The number of unit squares that cover the surface of a closed-form is the figure's area. Square meters and other similar units are used to measure area.

The area of the track is found as;

\rm A=\frac{\pi}{4} d^2 \\\\ \rm A=\frac{3.14}{4} (100)^2 \\\\ A=7850 \ m^2

Hence, the area of the track will be 78501 m².

To learn more about the area, refer to the link;

Answer: 4 cups of milk

=============================

Work Shown:

2 & 1/2 = 2 + 1/2 = 2+0.5 = 2.5

2.5 cups of milk makes 5 servings

x cups of milk makes 8 servings

Divide the cups of milk over the servings to get this proportion

2.5/5 = x/8

Cross multiply and solve for x

2.5/5 = x/8

2.5*8 = 5*x

20 = 5*x

5*x = 20

x = 20/5

x = 4

You need 4 cups of milk to make 8 servings
