I Have a circular baking tin 24 cm diameter and 8 cm height? What is the volume?

Good question.

The area of a triangle is the base times the height.

A=b * h, where A is the area, b is the length of the base, and h is the height.

So what three sets of numbers multiply to 24.

To do this, we can factor 24, starting from 1 going up to approximately the square root of 24, which is 5. After this, the numbers will just reverse.

1 * 24
2 * 12
3 * 8
4 * 6

Pick any three of these and make triangles with the base being one number, and the height being the other number. Then connect the ends of the line to the top of the height line. You can move the height along the base and create many many different triangles with an area of 24 cm squared.

Good luck,

Paul

You give only two values for the dimensions, so it must be a cylinder with a radius r=230/2 mm= 115 mm= 11.5 cm
and a height of h= 450 mm =45 cm
The volume for your right circular cylinder is V=PI*(r^2)*h=PI*(11.5^2)*45 cm^3=?
Divide the result by 1000 to convert the volume to liters (1 L =1000 mL=1000 cm^3)

Volume of right circular cone
V=(Area of base)* height/3=PI*(2.2^2)*(4.3)/3 cm^3
Finish the calculation.

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.

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.

Volume of a right circular cylinder of radius r and height h is
V=PI*(r^2)*h
Figure out which is the radius and which is the height, then plug in the formula above. Result is in cm^3

Is this a right circular cone or a right circular cylinder?
Volume of cylinder= Pi*(r^2)*h
Volume of cone is 1/3 of volume of cylinder with same height and radius.
Solve for h
h=(Volume)/(PI*r^2) for cylinder

21 cm is 8-1/4 inches. You could use an 8 inch blade or 7-1/4. But the diameter of the blade is not the critical thing. You must have a correctly fitting hole in the blade to mount on the saw shaft. Standard English size of the hole is 5/8 inch. Just take your saw with you to the store and try a blade on it. If the hole is a nice fit, your are good! (You posted this under circular saws, so I assume your saw is portable.)

When you have to deal with problems of this sort, you usually are given recipes or mathematical formulas which you apply to find the result. It so happens that for the volumes of cylinders, the formula to use is
Volume = Area of the base times the height=Ab*h
If the cylinder is circular, then the area of the base is that of a disk, Ab=PI*r^2`where r is the radius.
In your case, you are given the diameter (twice the radius) and the height.
Volume =PI*h*(6.2/2)^2, the unit being cm^2

To type in the value of PI, press [2nd] [^] (the latter is key under CLEAR, and above the division sign.
To raise a number to power 2 (to square it), use the key marked x with a superscript 2, or x with a raised 2.
After you have typed in all necessary ingredients in the formula, press the [ENTER] key and the calculator will give you the result.

Now, it is your turn to do some mathematics.

that would be 3.14159 X 225mm squared X 900mm

or pi X Radus X Radus X height

that =
143,138,694 cubic mm

or 143,139 cubic cm

or 0.143138694 cubic meters

or 8734.859 cubic inch
