Home work help! Maths Project>>>>> circle and pi relationship Please provide answers for the following questions: (1)What is the relationship...

(1) The relation which describes the length of the circle, that means the circumgference is:

L = 2*pi*R, where L is the circumference, pi = 3.14... and R is the radius of the circle.

(2) First pi is the measure, in radians, of 180 degrees.

All relations concerning features of the circle are using the pythagorean number, pi = 3.14...

For example, the formula for finding the circumference of the circle, stated to the point (1) is using the number pi:

L = 2*pi*R

Another example is the calculus of the area of the circle:

A = pi*R^2

The features of all geometric figures are calculated depending on the pythagorean number pi.

The volume of a cylinder:

V = pi*R^2*h, where h is the generatrix of the cylinder.
