What is the equation for the cirrcumfrice of shapes?
circumference of a circle = 2*pi*radius or diameter*pi
What is the number that you use to find pi?
the number is that you use for pi is 3.14 the number is that you use for pi is 3.14
What does pi means in mathimthics?
If you draw a circle and then create a square around it so all four sides touch, pi is the number that represents the ratio of the sizes of the two shapes.
What is pi about?
Pi is the number you have to use to solve many circle equations. If you want to find the area of a circle, use radius squared times pi. For the circumference, use diameter times pi.
Do all shapes with fixed area have the same perimeter?
No. For example 1 sq. f. circle has 2*Pi*(1/Pi)^0.5 perimeter and 1 sq. f. square has perimeter of 4. As you can see 2*Pi*(1/Pi)^0.5 does not equals 4.
What is the realationaship between a sphere and cylinder?
They are both 3D shapes and use pi in calculating area or volume
How do you figure out the area of shapes using Pi?
i think you do d x pi

What are all the geometric shapes that use Pi for calculating their volume or perimeter or area?
Any shape based on circles will use pi. eg - circumference/ area of cirlcles/ half circles etcSurface area/ volume of cylinders, spheres, hemispheres, cones, truncated cones"donut" shapes etc
What is the number that you use to find pi?
the number is that you use for pi is 3.14 the number is that you use for pi is 3.14
How is pi worked out?
Pi is the ratio between the circumference of a circle and its diameter. The first and most obvious way to find pi is to measure both the circumference and the diameter. This gives a very rough approximation. A second way is to use geometry. By fitting regular shapes with large numbers of sides both around and inside the circle we can narrow the boundary for the potential value of pi. The most accurate way to find pi is to do with its use in certain very complex formulae. Computers are required to determine pi to an infinite decimal place.
What is the diameter if the circumferance is 56 inches?
Just divide 56 by pi. Pi is approximate 3.14; or use the "pi" key on your scientific calculator.Just divide 56 by pi.
