Step-by-step explanation:
The volume of a cylinder is calculated if you multiply the area of the base by its height.
Think about it as if you are calculating the area of a circle, and then giving it a height. That's exactly what you need to do. The diameter of the base is 9cm and the height is 15cm.
So,
V = 1215π/4 ~= 954.25 cm^3

Answer:
Step-by-step explanation:
Midpoint: (0,3)
Endpoint: (6,-3)
Use the midpoint formula:
Since you already have the midpoint and you need an endpoint, let the unknown endpoint be (x,y). Take the midpoint formula apart:
and
are the coordinates of the midpoint. Enter the known values of the midpoint into the equations:
Now enter the known endpoint values:
Solve for x. Multiply both sides by 2:
Subtract 6 from both sides:
Now solve for y. Multiply both sides by 2:
Add 3 to both sides:
Now take the values of x and y and turn into a point:
Finito.
