Question

For any circle the ratio of the radius to the circumference is approximately:

a. 6 to 1
b. 3 to 1
c. 1 to 3
d. 1 to 6

Answer 1

1 to 6

Answer 2

C = 2pi*r

r/C = r/2pi*r = 1/2pi

Answer 3

\[2\pi/1\]

Answer 4

reverse it

Answer 5

can you explain please

Answer 6

So we want the ratio of the radius to circumference. radius is r and circumference is C=2 pi r

radius:circumference
= r:2pi*r I divide both sides by r to get
= 1:2pi
= 1:6.2831...

So the answer will 1 to 6 as that it the closest.
