Answer
A: 125 Ft
B: 14 Ft
C: 139 Ft
D: (0, 139)
E: (x)^2+(y-139)^2=15625
Work Step by Step
A: Radius= Diameter/2 thus Radius = 250/2
=125
B: Max height - diameter = Height to bottom of wheel, thus 264-250=14
C: Radius+ Height From Ground = (y) center, The radius (125) + Height from ground (14) = 139. So the center is 139 ft high.
D: We assume the origin is when x=0. So the coordinate is just (0, y-intercept of center) which plugged in is (0, 139).
E: Remember the equation of a circle: (x – h)2 + (y – k)2 = r2, with the center being point (h, k) and the radius at "r". Plugging in our center and radius, we get (x-0)^2 +(y-139)^2=125^2
