the circumference formula uses pi and the formula is pi (3.14) times what ever the diameter is and that's one formula i know and I'm in fifth grade

a formula that uses pi is the circumference and area of a circle and every polyhedron that has a circle

Pi = circumference/diameter

you can use 2 formulas... 2 x pi x radius or pi x diameter - dont forget that pi is always 3.14 unlsess said otherwise. :) hope this has helped.......

use the formulas pi*diameter 3.14*72 then simplify 226.08

Yes. Some examples of formulas that contain pi (∏) are: (area of a circle) = ∏r2 (Circumfrance of a circle) = ∏d

All around the world, because pi is used in many formulas.

They are: 2*pi*radius or as diameter*pi

There are thousands of formulae which use pi:Circumference of circle = 2*pi*radiusArea of circle = pi*r^2Area of ellipse = pi*semiaxis1*semiaxis2Surface area of sphere = 4*pi*r^2Volume of sphere = 4/3*pi*r^3pi also appears in some of the most common statistical distributions: the Gaussian (or Normal) as well as Student's t-distribution.

the other formulas involve non-circular shapes
