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 ?

(pi)R squared (Fixya won't let me use the sign for Pi)

Area of a circle=pi*radius^2 or pi times radius times radius

example: suppose the radius of a circle is 10 inches, then the Area of the circle would be pi times 10 times 10 or 100*pi

pi represents the circumference (distance around) of a circle / diameter and for any circle is constantly the same number which is approximately 3.14

so in my example 100*pi=100*3.14 or 314 square inches

Area of a circle=pi*radius^2 or pi times radius times radius

example: suppose the radius of a circle is 10 inches, then the Area of the circle would be pi times 10 times 10 or 100*pi

pi represents the circumference (distance around) of a circle / diameter and for any circle is constantly the same number which is approximately 3.14

so in my example 100*pi=100*3.14 or 314 square inches

Since the area of a whole circle is pi times the radius squared, the area of half the circle is one half times pi times the radius squared.

The circumference of a circle is given by the expression

Circumference= 2* PI* Radius of circle

**C=2*Pi*R**

The area is given by

**Area of a disk with radius R** **= Pi* R*R** or **PI*R^2**

**Area= PI*R^2**

Circumference= 2* PI* Radius of circle

The area is given by

Come on princess. Use the formula for the area of a circle: Area=PI*D*D/4

where PI can be entered using a key on the calculator, and D is the diameter.

Area =100*Pi cm^2 or about 314.159 cm^2

where PI can be entered using a key on the calculator, and D is the diameter.

Area =100*Pi cm^2 or about 314.159 cm^2

Well it depends. If the hexagon is irregular (sides are not equal) there is no formula to calculate the sides as they can have arbitrary values. You must measure them.

If the hexagon is regular you may be able to relate the measure of a side to the radius of the circle in which it is inscribed. If you have the radius of the circle, the side is equal to the radius. If you have the value of perimeter you divide that value by 6.

There is also a formula that relates the area of the hexagon to the measure of the side s. The formula is Area=(6/4)(s^2)cot(PI/6), where cot is the cotangent function, its angle is in radian. In degrees Pi/6 is 30 degrees.

Pi is a mathematical constant whose value is the ratio of any Euclidean plane circle's
circumference to its diameter; this is the same value as the ratio of a
circle's area to the square of its radius. It is approximately equal to
3.14159265 in the usual decimal notation.

You sort out the formula for the surface you have to calculate then substitute the numerical values for the variables (sides, bases, heights), the constants if any (pi, etc.) an press = to get the result

Ex Square with side= 2m

Surface area=side^2

Area : 2 [X^2][=] result is 4 m^2

Circle of radius r=3 cm

Area: Pi* 3[^2]=28.27 cm^2

You cannot have a semicircle that has a diameter of 2.500 mm and a radius of .425mm and a circumference of 3000mm

Circumference is equal to pi times the diameter. pi is = 3.14

The radius of a circle is always 1/2 the diameter

Area of a circle is pi time the radius squared

Entire books have been written on this topic; it's far beyond the scope of a single post. I would recommend the book "The History of pi" by Petr Beckmann for a readable, non-technical introduction.
