1.
What is the area of one of the blue half circles? HINT: Remember, Area = pi x radius squared.
So you will need to use the 40 (this is the diameter so make sure you find the radius). Then
since you only want a half circle, you will need to divide it by 2. SHOW ALL WORK!

Answer 1

Depends on how the teacher wants the answer:

400π (in terms of pi) or 1256.6 (rounded to tenths place)

Explanation:

40/2 = 20, the radius of one of the blue circles

Use the formula: πr², but divide it by 2 because it is a semicircle

π20² = 400π = 1256.63706

Let me know if you need help rounding it if the question asks you to.
