Find the volume of the cylinder.
The formula for the volume is V=Pr^2h but it give a diameter. Does this mean first I divided the diameter by 2?
let D = diameter
Radius is half the diameter.
So,
r = (1/2) D
Substitute that in the given equation and then you will have an equation using the diameter.
Yes, you are correct. In order to use the formula V = πr^2h, you need to have the radius, not the diameter, of the cylinder. The radius is the distance from the center of the circular base to the edge of the base.
To find the radius from the given diameter, you divide the diameter by 2. So, if you have the diameter of the cylinder, divide it by 2 to get the radius, and then you can substitute the radius value into the formula to calculate the volume of the cylinder.
