**If you know the circumference of a circle which step(s**

27/11/1997Â Â· Remember that, diameter = 2 * radius and so circumference = pi * (2 * radius) = 2 pi * radius or simply C = 2 pi r This is the way you'll find it in most books, in terms of the radius. -Doctor Luis, The Math Forum Check out our web site!... Once you have that figure, you can calculate the circumference. The circumference is equal to pi times the diameter, or two pi times the radius. Pi is equal to approximately 3.1415 which is close enough for all usual purposes.

**How do you find the circumference if you know the radius?**

26/02/2009Â Â· plug in what you know to find what you don't we know the circumference, and we know pi, lets get the diameter 16cm/3.14=diameter (diameter = 5.0955414cm) now we know the diameter so we can get the radius radius= 5.0955414cm/2 radius=2.5477707cm The height of the cylinder means absolutely nothing, by the way. That only matters if you want volume. Machidiel Â· 10 years ago . 1. â€¦... Finding the relationship between circumference and area : We can use what we know about circumference and area of circles to find a relationship between them. Start with a circle that has radius r.

**How do I find the circumference of a circle if I know the**

You cannot measure the radius of a circle, since you do not know its center. However, you can determine the center of the circle. Suppose you place a bottle or jar cap on a sheet of paper and draw the circle by running a pencil round the edge.... A circular swimming pool has a radius of 14 m. Find the circumference of the pool. Solution: A circular flower-bed has a radius of 9 m. Find the circumference of the flower-bed. Solution: So, the circumference of the flower-bed is 56.5487 m. Key Terms. circumference

**How do you find circumference if you have the radius?**

You need to know the circular length of your garden in order to be able to decide how many bricks to buy. Also, tires of vehicles are circular. If there is a particular distance that needs to be covered and if the rim of the tire is known, then it would be possible to calculate the number of rotations of the tire required to cover the distance.... Explanation: First, you will need to work backward from the circumference to find the radius of the circular enclosure. Now we know what the radius is, we can calculate the surface area of â€¦

## How To Find The Circumference If You Know The Radius

### A circular swimming pool has a radius of 14 m. Find the circumference of the pool. Solution: A circular flower-bed has a radius of 9 m. Find the circumference of the flower-bed. Solution: So, the circumference of the flower-bed is 56.5487 m. Key Terms. circumference

- 9/01/2008Â Â· Above are correct. However a good piece of information for you to remember. In a circle, if you are given any one of the following, radius, diameter, circumference, or area.
- A. Circumference = Ï€ * diameter or Ï€ * 2*radius (diameter = 2 * radius). So you would divide by Ï€ to get the diameter, then divide by 2 to get the radius.
- Once you have that figure, you can calculate the circumference. The circumference is equal to pi times the diameter, or two pi times the radius. Pi is equal to approximately 3.1415 which is close enough for all usual purposes.
- If you know the diameter, it is 2 times the radius, so just divide by two, to get the radius, or use this formula: Ï€ x diameter. The calculation result is in the unit in which you measured the circle radius â€¦
