we do not regularly use pi in our everyday life. But suppose you some how end up one day painting a cylindrical room. You will have to use pi to find out the circumference or surface area of the room you will have to use pi to figure out how much area you will have to paint
No. The square root of negative one is an example of an imaginary (not real) number. Pi is irrational, but real.
Finding the area of a circle: pi*radius2 Finding the circumference of a circle: 2*pi*radius or diameter*pi Finding the surface area of a sphere: 4*pi*radius2
a formula that uses pi is the circumference and area of a circle and every polyhedron that has a circle
Yes, it is.
