When graphing Y=3X-5 you want to start looking at the Y axis or the vertical line that goes up and down. You need to draw your first point or dot on the vertical line starting at negative five (-5). Then you start to go up 3 boxes and over 1 box or to the right one box because the equation has 3x in it . So after starting at negative 5 you want to travel up 3 and over 1, up three and over 1, do this until your graph can no longer go on or is not bug enough. Did i answer your question?
Answer:
(x +3)^2 + (y -3)^2 = 3^2
Step-by-step explanation:
Your first task is to find the center.
The longest possible line of the circle goes from (-3,0) to (-3,6)
So the center is at the midpoint of these two points.
The midpoint is at (-3 - 3)/2 , (6+ 0)/2 or (-3,3)
That gives you the center of the circle.
So far what you have is
(x +3)^2 + (y -3)^2 = r^2
Now the distance of the center to the bottom point is (-3,3) to (-3,0)
r^2 = (x2 - x1)^2 + (y2 - y1)^2
x2 = - 3
x1 = - 3
y2 = 3
y1 = 0
r^2 = (-3 - -3)^2 + (3 - 0)^2
r^2 = 3^2
The entire answer is
(x +3)^2 + (y -3)^2 = 3^2

Volume of a cone V = pi * r * r * h / 3
so V = 45, r = 2 therefore 45 = 3.14 * 2 * 2 * h /3 => 45 = 3.14 * 4 * h /3
=> 135 = 3.14 * 4 * h => 33.75 = 3.14 * h => 10.75 = h
height = 10.75 cm rounded to 2 decimal places
