At shop A, 2 pounds of crawfish costs $6. At shop B, 5 pounds of crawfish costs $15. Jacob says the cost per pound is the same at both shops. Is Jacob correct? Explain your reasoning.

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

what's the question?

step-by-step explanation:

there is no question.

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
