The x-axis is a horizontal line with the equation y = 0. The line parallel to the x-axis through the given point is y = 4, which is another horizontal line which has a slope of 0, which is true of any horizontal line.
So a diameter is twice the radius The formula is: V = π(r^2)(h/3) the half of 300 is 150, so the radius is 150 V = π(150^2)(150/3) V = π(22500)(50) V is about <span>3534291.74</span>
