Answer:
20.25 pi
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
9 pi = 2 * pi *r
Divide each side by 2pi
9pi / 2 pi = 2 pi r / 2 pi
4.5 = r
Now we can find area
A = pi r^2
= pi ( 4.5)^2
20.25 pi

Y = k/x
13 = k/6
k = 78
y = k/x
8 = 78/x
8x = 78
x = 78/8
x = 9.75
You can divide. i believe
