22 lip 2024 · You can calculate it as follows: If you know the radius or diameter of the circle, the area of the circle formula is: a = πr² = π × (d / 2)². If radius and diameter are unknown, you can calculate it from the circumference: a = c² / 4π. If you are interested in calculations of some fraction of a circle, check:
Use this calculator to easily calculate the circumference of a circle, given its radius in any metric: mm, cm, meters, km, inches, feet, yards, miles, etc. If you know the diameter, first divide it by two to get the radius.
22 lip 2024 · Use the formulas to calculate the circumference and area: c = 2πr and A = πr². The circumference should equal c = 2π × 8 cm = 50.265 cm . The area should equal A = π × (8 cm)² = 201.06 cm² .
Find the circumference of a circle given the radius, diameter, or area using our circumference calculator. Plus learn the formulas to find it.
Circumference formula is evaluated by multiplying radius of the circle with 2 and π. The formula for circumference can be expressed as: C = 2πr. Where: C represents the circumference, r is the radius of the circle, and. π refers to the value of 3.14159.
The circumference of a circle for any given variable can be calculated using the formula: C = 2πr = πd. Where: π = pi = 3.14159. In reverse to determine the radius and diameter of a given circular shape, we can use the circumference calculator but for manual calculations here are formulas for the radius & diameter.
