Answer 2

To find the area of a sector, given the area of the circle, just multiply the area of the circle by the ratio of the angle and 360 degrees. That's:
blue sector area=25π(45/360)=3.125π

Answer 3

area = 25π
area of a sector = central angle/360 * area
central angle of blue region = 45/360*25π

Answer 4

so the answer is B?

Answer 5

ita C

Answer 6

3.125π=9.817.
