   Circumference of a Circle Formula. The Circumference (or) perimeter of circle = 2πR. where, R is the radius of the circle. π is the mathematical constant with an approximate (up to two decimal points) value of 3.14. Again, Pi (π) is a special mathematical constant; it is the ratio of circumference to diameter of any circle. where C = π D. C ...

   • To calculate the circumference of a circle, multiply the diameter of the circle with π (pi). The circumference can also be calculated by multiplyin...
   • The formula for circumference = diameter × π Or, diameter = circumference/π So, the diameter of the circle in terms of circumference will be equal...
   • Circumference = 2×π×r C = 2×3.14×24 C = 150.72 inches
   • Step 1: Find the radius using the area of the circle formula (A = πr 2 ). Step 2: Now, substitute the radius value in the circumference formula (C...
   • If the area of a circle is given, then the formula to calculate the perimeter or a circumference of a circle is given by: C = 2√(πA) units.
   • We know that, Circumference = 2πr = 2π(3) = 6π Therefore, the circumference of a circle is 6π cm, if its radius is 3 cm.
   • As we know, Circumference of a circle if its diameter is given = π × d units. Substituting d = 7 cm in the formula, we get C = π × 7 = 7π units.
