Question about Texas Instruments TI-83 Plus Calculator

I have no idea about your knowledge of calculus. But the solution requires calculus (I am in no mood to introduce a Delta V and Delta t and let Delta t approach zero.)

The formula is V = Pi * R^2 * H where

R: radius

H: height

V: volume

So you need the radius and height in feet, and plug them into this formula. Or you can enter what you know, in feet, to this calculator, and it will give the unknown

Hi Paula:

A mathematical logic question.

You need to get all of the measurements in the same units.

- A cubic yard is 1 yard x 1 yard x 1 yard

- equals 3 ft x 3 ft x 3 ft

- equals 27 cubic feet,

so once you have the volume of the pipe in cubic feet, you divide by 27 to get the volume in cubic yards.

- Volume of a cylinder (the pipe) is the cross sectional area X length.

- Area equals Pi x r squared.

- equals 22/7 x 1 x 1

equals 3.14#####

times length (20)

equals 62.857### cubic feet volume

divide by 27 cubic feet

equals 2.328### cubic yards.

- The answer is always the easy part.

- what is important is knowing exactly what the question is, and

- determing what calculations are needed to get the answer.

Wasn't that better than if I'd just said 2 1/3 cubic yards?

Cheers

The radius or the volume of the space?

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.

V=(Area of base)*height.

If cylinder is circular Area of base =PI*radius^2=Pi*r^2

Volume is

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

volume is calculated by finding the area multiplied by the length or height . That is Pi X radius squared X length

example --tube 6"dia 12"long what is the volume?

Example 3.1417 X radius 3" Squared =3.1417X9sq " = 28.2740sq" X length 12" =338.688 cubic"

If you want the volume of an engine cylinder , it is the same formula and the length is the stroke of the piston ( distance from TDC to BDC )

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

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,

If you choose the height, then to solve for r

r^2=(3V)/(Pi*h)

and

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.

A pipe can be seen as two cylinders, one of "air" sitting inside the other, in this case lead.

To get the volume of a pipe you thus subtract the volume of the "air" cylinder from that of the lead cylinder.

Volume of a cylinder = area of circular cross section (or pi times square of the radius) times the height (or length) => ? * r2 * h

Volume of a pipe = Volume of cylinder 1 (outer diameter) - volume of cylinder 2 (inner diameter).

In this case; Volume of outer cylinder => inner diameter 1/2" (0.5") + pipe thickness 1/4" (0.25") = 3/4" (0.75") divided by 2 to get radius = 0.375".

3.14 (?) * 0.375 * 0.375 * 120(10 feet) = 53.01438 in3

Volume of inner cylinder => inner diameter 1/2" (0.5") divided by 2 to get radius = 0.25".

3.14 (?) * 0.25 * 0.25 * 120(10 feet) = 23.56194 in3

Volume of lead in this pipe = 53.01438 - 23.56194 = 29.45244 in3

Hope this helps ;)

Well if you go off of the volume, which is how much an item is made of versus how much space it takes up which is area, for the cubed beam you let 150 cubic feet versus the cylinder which is 125.6 cubic feet. The cylinder uses less product.
