Circumference = 2(pi)(radius)
Circle 1: 48=2(pi)(radius)
24/pi = radius
Circle 2: 12 = 2(pi)(radius)
6/pi = radius
Area = (pi)(radius)^2
Circle 1: A = (pi) (24/pi)^2
= 576 / pi
Circle 2: A = (pi) (12/pi)^2
= 144 / pi
576/144 =
4 times greater

Rearrange them to slope-intercept form
y = 7x + 2
y = -(1/7) x + 8
product of their slopes is 7 * -1/7 = -1 so they are perpendicular
