Answer:
- 24 cm²
- 6400 -1600π ≈ 1373.45 square units
Step-by-step explanation:
1. You can look at this several ways.
It can be considered to be a stack of 1+2+3 = 6 squares that are 2 cm on a side, so have a total area of 6 × (2 cm)² = 24 cm².
You can lop off one of the squares sticking out and put it into the empty corner to form a 6 cm by 4 cm rectangle with an area of (6 cm)(4 cm) = 24 cm².
You can consider it to be a 6 cm square with 3 squares cut out of it that are 2 cm on a side: (6 cm)² -3(2 cm)² = (36 -12) cm² = 24 cm².

2. The shaded area is the difference in areas of a square 80 units on a side and a circle of 40 units radius. If we let d represent the side dimension of the square, then the area formulas are ...
Square area = d²
Circle area = π(d/2)²
So the difference area is ...
shaded area = d² -(π/4)d² = d²(1 -π/4)
For d=80, the shaded area is ...
shaded area = 80²(1 -π/4) = 6400 -1600π ≈ 1373.45 square units
16+5=21
21/3=7

Using the given recipe, he will need 6 cups of milk to make 18 servings.
<h3>How many cups of milk will Miguel need for 18 servings of pudding?</h3>
We know that the recipe for 6 servings, calls for 2 cups of milk.
Miguel wants to do 18 servings, Then he needs to use the recipe:
18 = x*6
Solving the linear equation for x:
x = 18/6 = 3
So he needs to use his recipe 3 times.
And we know that for 6 servings he needs 2 cups of milk, then for 18 he needs:
3*(2 cups) = 6 cups of milk.
Using the given recipe, he will need 6 cups of milk to make 18 servings.
