Suppose that circles a and b have a central angle measuring 40°. additionally, circle a has a radius of
5/2 ft and the radius of circle b is
9 /2 ft.
if the measure of the sector for circle a is 25/36 π ft2, what is the measure of the sector for circle b?

a)

2
9
π ft2

b)

4
9
π ft2

c)

9
4
π ft2

d)

9
2
π ft2

C. .

Step-by-step explanation:

We have been given that circles A and B have a central angle measuring 40°. Additionally, circle A has a radius of  5/2 ft and the radius of circle B is  9 /2 ft.  

Let us find measure of the sector of circle B using sector area formula.

Let us substitute our given values in sector area formula.  

Therefore, the area of sector for circle B will be and option C is the correct choice.

the last choice
