How to find the diameter of a circle with circumference?
Answer: Diameter of a circle can be calculated by dividing the circumference by π.
Let's look into the relationship between circumference of a circle and its diameter.
Let the radius and the diameter of the circle be 'r' and 'd'.
Let the circumference be 'C'.
Circumference of a circle = 2 × pi × r
⇒ C = 2πr
Diameter = 2 × radius
⇒ d = 2r
Thus, C = πd
⇒ d = C/π
