9-(.5)^(4)/48
= 9-0.0013020833
=8.9986
Because it would be easier to follow the formula that you were given to solve.
Answer to the problem you are asking is d
Answer:
Step 5 was not correct
Step-by-step explanation:
Tyra cannot take x and 6 common and then remove those valuse.
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=4/7--------> rB/rA=7/4
LA=(1/2)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-----> [(1/2)π*7/4]----> 7/8π
the answer is
the length of the intercepted arc for circle B is 7/8π
