Which of the following ratios are equivalent to the ratio 3:4?
12:16 6:8 4:3 For one of the equivalent ratios, justify your reasoning

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

what graph

step-by-step explanation:

the answer to your question is minor arc.

arc length = radius * x ( in radians)

6 * pi = 18 * x

divide by 18 on each side

6 pi / 18 = x

pi/3 = x

the angle is pi / 3 radians

or   60 degrees
