please give me the best answer.

Answer 1

2.5pi

Answer 2

that is 1/4 of 10

Answer 3

Since the degree of the arc is 90 degrees, and a circle is always 360 degrees, you can determine that the area is 1/4 of 10, which is 2.5in^2.

Answer 4

not 2.5pi it is 2.5in2

Answer 5

since its 90 degrees, its a fourth of a circle

Answer 6

so 10/4 is 2.5

Answer 7

i messed up for the pi thing, there's no pi since the area is 10, not 10pi
