What is the circumference with a radius of 6?
Finding the Circumference: If r = 6 cm, the the circumference is c = 2π(6) = 12π cm, if writing in terms of π. If you prefer a numerical value, the answer rounded to the nearest tenth is 37.7 cm.
How do you find the circumference when given the radius?
To calculate the circumference, you need the radius of the circle:
- Multiply the radius by 2 to get the diameter.
- Multiply the result by π, or 3.14 for an estimation.
- That’s it; you found the circumference of the circle.
What is the circumference when the radius is 3?
Explanation: The formula for finding the circumference is 2πr . We can plug in 3 for r, getting 2π3 .

What is the circumference of a circle with a radius of 1m?
To calculate the circumference of a circle with a radius of 1 meter, simply follow those steps: 1 Multiply the radius by 2 to get the diameter of 2 meters. 2 Multiply the result by π, or 3.14 for an estimation. 3 And there you go; the circumference of a circle with a radius of 1 meter is 6.28 meters.
How to find the area of a circle from the circumference?
To find the area of a circle from the circumference, follow these steps: 1 Divide the circumference by π. 2 Divide the result by 2 to get the circle’s radius. 3 Multiply the radius by itself to get its square. 4 Multiply the square by π, or 3.14 for an estimation. 5 You found the circle’s area from the circumference.
How do you calculate the radius of a circle in Excel?
This tool will calculate the radius of a circle from the circumference, and will convert different measurement units for circumference and radius. Formula. The formula used to calculate the circle radius is: r = C / (2 · π) Symbols. r = Circle radius; C = Circle circumference; π = Pi = 3.14159… Circumference of Circle
What is the proportion between radius and diameter?
Circumference to diameter. You have probably noticed that, since diameter is twice the radius, the proportion between the circumference and the diameter is equal to π: C/D = 2πR / 2R = π. This proportion (circumference to diameter) is the definition of the constant pi. It is used in many areas, such as physics and mathematics.
