Divide the circumference of a circle by pi (approx 3.1416) to find its diameter.
Divide the circumference by 3.14159265 (3.14 for rough approximation) to find the diameter of a circle.
Divide the circumference by 3.14159265 (3.14 for rough approximation) to find the diameter of a circle.
Circumference = (diameter) multiplied by (pi)
Divide the circumference by pi (pi = 3.14159 or rounded to 3.14 for rough approximation) to find the diameter of a circle.
Circumference = 2*pi*radius or pi*diameter Circumference = 36pi inches
pi X diameter finds the circumference so circumference divided by pi will leave the diameter. half the diameter to find the radius
To find the diameter of a circle, you will either need to know the area or its circumference. If you know the area: diameter = 2 x squareroot(area / Pi) If you know the circumference diameter = circumference / Pi
Diameter = Circumference/pi
diameter = circumference/pi
You cannot find the diameter of something from its circumference unless it is a circle and, in that case, diameter = circumference/pi
Circumference = Pi * diameter
Circumference in terms of pi = 2pi yards Area in terms of pi = pi square yards
Divide the circumference by Pi to find the diameter.
Circumference = diameter(pi) so divide the circumference by pi to get the diameter.
Diameter = radius * 2 Circumference = pi * diameter.
circumference = π x diameter = 9π m ~= 28.3 m
