### What is the cubic yard of a circle that is 10.82feet diameter x 16inches deep?

the formula for volume of a cylinder is Volume = pi × r2 × h
but if you arent math savvy, first you convert your units so they are the same. all you have to do is change 16 inches into 1.3 feet and divide your diameter (10.82 feet) by 2 to give you the radius (5.41 feet)
plug in those values here:
https://www.bing.com/search?FORM=U312DF&PC=U312&q=volume+of+a+cylinder

and you will get 119.5 cubic feet

then convert cubic feet to cubic yards here:

### Calculating pond capacity using volume of a cylinder in gallons?

the formula to calculate volume is surface are multiplied by the height ( depth)
that is PYE times the radius squared multiplied by the depth of the pond
1 cubic ft of volume = 7.48 gallons

### What formula do you use to calculate cylinder volumes

Volumes are any three dimensional measurement...

I Seriously doubt that I could get Pi ("pie") to print...
But I'll just GIVE YOU the number (much simpler)
Pi = 3.14159

Inches, feet, yards or meters.. all the dimensions need to be in the same values... So if you have an inch "ruler"...
That is just fine...!!

Your first step would be to determine the diameter of the inside of your cylinder in inches...
CONVERT that to the RADIUS by DIVIDING by 2...
Multiply that RADIUS by itself and then by 3.1416 = area of circle in INCHES... (radius "squared" x Pi = (square inched)

Then MULTIPLY the height (in inched) by the AREA...
EQUALS THE VOLUME in CUBIC INCHES...!!

But I'll just GIVE YOU a REFERENCE (much simpler)
mathematical constant ?
Area of circle

### How many cubic yards would it take to fill in. 20' x 2' diameter

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

### 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.

### Volume of a cylinder formula

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

### If a lead pipe 1/4in.thick has an inner diameter of 1/2in.,find the number of cubic inches of lead in a pipe 10ft.long

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 ;)

### Which would require more steel, acubical beam wit a length of 25ft, a width of 2 ft, and a height of 3ft or a cylindrical column with a height of 10ft and a radius of 2ft

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.
