Using Desmos, I have the graph below:
Also, the slope is 1.5 because 6/4=1.5.
It would take 471 weeks. First, square the radius. Then divide the height by three. Multiply the square radius and the answer you got after dividing h by 3. Then multiply that answer by 3.14. Usually, you're done, but for this problem take the extra step and divide it by 12,000.
So hmmm notice the picture below
recall the "inscribed angle" theorem, an angle inscribed is half the intercepted arc
now, the line BA goes through the center, and to each end, thus is a diameter, the point of tangency, where a tangent hits the diameter or radius of a circle, is always a right-angle
