Both circle a and circle b have a central angle measuring 140°. the ratio of the radius of circle a to the radius of circle b is 2 3 . if the length of the intercepted arc for circle a is 3 4 π, what is the length of the intercepted arc for circle b?

Let 

rA> radius of the circle A

rB> radius of the circle B

LA> the length of the intercepted arc for circle A

LB> the length of the intercepted arc for circle B

we have that

rA/rB=2/3> rB/rA=3/2

LA=(3/4)π

we know that

if Both circle A and circle B have a central angle , the ratio of the radius of circle A to the radius of circle B is equals to the ratio of the length of circle A to the length of circle B

rA/rB=LA/LB> LB=LA*rB/rA> [(3/4)π*3/2]> 9/8π

 the answer is

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
