I have a circle of 4cm what is the diamiter?

What does the 4cm refer to?

If it's the diameter, then obviouly the diameter is 4cm.

If it's the radius, the diamter is 8cm.

If it's the circumference, the diamter is 4/pi cm.

What is the volume of a cone that has a radius of 3.5 and a height of 18.5?

Here is the formula for the volume of a cone. Use it to calculate the volume yourself.
Volume of cone =(1/3)(area of base)*(height)
If the cone is a right circular one
Volume =(1/3)(PI *radius^2)*(height)=(1/3)*Pi*[(3.5)^2]*18.5
assuming that the radius and the height are expressed in the same units. The result (after you calculate it) will be in cubic units.

Find the volume of a cylinder the radius is 8cm the height is 6cm what is the volume

Volume of right cylinder is
V=(Area of base)*height.
If cylinder is circular Area of base =PI*radius^2=Pi*r^2
Volume is V=Pi*(8^2)*6 cm^2
Finish the calculation.

What is the formula for finding the volume of a cylinder

The formula to find the volume of right prisms and right cylinders is
Volume=(area of base)*height
If the cylinder has a circular base, then the area of the base is PI*R^2
and the volume is Pi*(R^2)*H.
Here R is measure of the Radius, and H is the measure of the Height. R and H must be expressed in the same unit.

How do you calculate cubic feet?

You calculate a volume. If all the lengths, radii, heights are in feet the resulting volume is in cubic feet.
Example: Right rectangular prism with L=5 ft, W= 3 ft, height =1.5 ft
Volume =(5 ft)*(3 ft)*(1.5 ft)= (5*3*1.5) (ft*ft*ft)=22.5 ft^3

What size cone is needed to hold 150 gallons

You need a cone with a volume of 150 gallons.
The volume of a right circular cone is given by the formula
V_cone=(Area of base *height)/3
Since cone is circular , its base is a disk with a certain radius r. The formula becomes PI*(r^2)*h/3
As you see there are two variables, the radius and the height. There is an infinite number of combinations (radius, height) that will give you a total volume of 150 gallons. You can choose the radius (r) and solve for h, or you can choose the height then solve for the radius.
I suggest you convert gallons to cubic feet or to cubic meters then put
V=Pi*(r^2)*h/3 where V is the value of volume after conversion.
If you choose the radius, then to isolate h, h=(3*V)/(Pi*r^2)
If you choose the height, then to solve for r
and r=square root of (3V/(Pi*h))
Now, it is your turn to carry out the rest of the calculation.
It will consist of the value of the radius, and the value of the height.
If the cone is not right circular, the situation becomes more complicated.

How many tons in 3 cubic meters sq by 3inchs deep

I am sorry to say it but your units do not make sense: Units of volumes and areas are mixed up.
Let us try to make sense of it.
If you have some container whose base is 3 square meters (not cubic meter sq) and it has a height of 3 inches you can calculate its volume in cubic meters or in cubic inches or cubic feet. To do so convert the height in inches into meters and multiply the area of the base by the height in meters and you will obtain the volume in cubic meters. To get the volume in cubic inches convert the area of the base to square inches and multiply by the height in inches.

However, even after you have expressed the volume in one unit or another (m^3 or in^3) you cannot find the mass of the substance contained (be it in tons, tonnes or kilograms): You need to know the substance and more specifically its density or its specific gravity).
Please, reformulate your question and specify the substance that fills or would fill the volume. Without that information, nothing doing.
