We would need one other piece of information to answer it: EG. the angle of the slope, or the radius or diameter of the cone base, or perhaps, the volume of the cone would also help. We need just one of these aforesaid pieces of information in order to calculate height.
Circumference = 2*pi*radius or diameter*pi
First draw a circle using a compass. Now, use a piece of string to help measure the circumference of the circle. Now measure the diameter of the circle. To discover Pi divide the circumference by the diameter.
An example of conservation of mass is simply cutting up a cookie into pieces. Even though you now have more pieces, it still has the same amount of mass (how much matter is made of the cookie) as you did when it was all in one piece. :)
$5 gold pieces minted from 1795 through 1829 were 25mm in diameter. $5 gold pieces minted from 1829 through 1834 were 23.8mm in diameter. $5 gold pieces minted from 1834 through 1866 were 22.5mm in diameter. $5 gold pieces minted from 1866 through 1929 were 21.6mm in diameter. $5 gold pieces minted from 1986 through 2009 were 16.5mm in diameter.

You could use a pair of calipers. Alternatively, measure its circumference using a piece of string and divide the measure by pi.
CIRCUMFERENCE = pi x D = 3.14 x 12 = 37.68 feet
Like cutting up a round cake (each piece starting at the centre) into very thin pieces. Each piece looks very like a thin triangle. Now arrange them next to each other alternately with points up and points down. For very thin pieces it looks almost exactly a rectangle, with the short side equalling the radius, and the 2 long sides totalling the original circumference. So the length of the rectangle is half the circumference. So the area must be RxC/2. Now pi is defined by "circumference of a circle = pi x diameter" so use that in the above area formula to get area = R x pi x diameter/2. But diameter/2 is radius. So the area is pi x R x R = pi x R2.
Part of the circumference of a circle is an arc.
The plural form of the noun 'piece' is spelled pieces, just as in your question.
pi in mathematics is used to determine the circumference of a circle. if you take a piece of string the length of the diameter of the cicle it would go around the circle 3.14159265358978 times (pi).
