yes, it is correct perimeter = d * pi pi is the ratio between the perimeter and the diameter
pi
Circumference of a circle is 2 x Pi x the radius
The similarity in appearance between the symbol pi and the Roman numeral II is entirely coincidental.
area = pi*r2 where pi is the irrational number approximated by 3.14159
If you want an approximate answer, you can measure it with string. If you want an exact answer and know the radius, multiply by 2*pi to find the circumference.
Pi is the relationship between the diameter and the circumference of a circle.
pi X diameter = circumference of the circle.
yes, it is correct perimeter = d * pi pi is the ratio between the perimeter and the diameter
circumference = pi*diameter or pi = circumference/diameter
A circle does not have a circumstance. Assuming that you mean circumfernece, the answer is c = 2*pi*r
in the greek alphabet the letter P is the same as the pi symbol...i think

The circumference and diameter
area = pi*r2 where pi is the irrational number approximated by 3.14159
