pi X diameter = circumference of the circle.
Pi is the relationship between the diameter and the circumference of a circle.
The circumference of a circle is pi times the diameter. The area of a circle is pi times the radius squared.
yes, it is correct perimeter = d * pi pi is the ratio between the perimeter and the diameter
Circumference of a circle is 2 x Pi x the radius
The circumference is pi times the diameter.
diameter times pi(3.14159) equals cicumference
circumference of of circle / Radius of the circle
area = pi*r2 where pi is the irrational number approximated by 3.14159
Yes because: circumference/diameter = pi and circumference = pi*diameter
Area = (Circumference squared)/4 pi Circumference = 2 sqrt(Area times pi)
