then cross multiply which gives you
divide each side by 30 to make the x by itself
which gives you the answer x=40
An equation for this is 5b. 5 times the number of books (b).

Answer:
Step-by-step explanation:
distance between center and (1,-2) is
distance of the point from the center>radius of circle.
So it lies outside the circle.
Circumference = 2 x pi x r
So you have:
6.3 cm = 2 x pi x r
(6.3cm) / 2pi = r
r = 1.o
therefore: d = 2
