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.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

what is the answer?
