Answer:
314 cm ^ 2
Step-by-step explanation:
First do, 3.14 x 20 ^ 2
3.14 x 20 ^ 2 = 1,256
Then do, 1,256/4
1,256/4 = 314
Why 4?
This part of the circle is 1/4 of the entire circle.

this is only one possible answer. For example, instead of radius, you could have put diameter or circumference.
Answer:
Parallel segments → 1
