if I have the circumference of a circle how do I find the diameter, and how do I find the radius
assistance needed
The formula for finding diameter is:
Circumference = pi * d
Therefore, insert your circumference, and divide by pi or 3.14 to get the diameter.
For radius:
Circumference = 2pi * r
So, insert your circumference and multiply pi by 2. Then divide the circumference by 2pi to get your radius.
Hope I helped! :-)
Diameter = Circumference/pi
Circumference divided by Pi = Diameter
Diameter divided by 2 = radius
circumference = 62.8 meters
using pi= 3.14
C = 62.8/ 3.14
= 20 meters
diameter =20 meters
d= 20 meters
r= 20/ 2
r=10 meters
thank you it was a great help
34yds find the circumference
34 yards for radius or the diameter?
cuz it could either be
(34x2) x 3.14= 213.52 yds
or
34 x 3.14= 106.76 yds
thats why you gotta state wether its diameter or radius
To find the diameter and radius of a circle given its circumference, you can use the formulas:
1. Diameter (d) = Circumference (C) / π
2. Radius (r) = Diameter (d) / 2
Here's a step-by-step explanation of how to find the diameter and radius:
1. Start with the given circumference value of the circle.
2. Divide the circumference value by π (pi). Pi is an irrational number approximately equal to 3.14159. This step gives you the diameter, which is twice the length of the radius.
3. Divide the diameter value by 2 to find the radius. The radius is half the length of the diameter.
Let's go through an example to illustrate this.
Example:
Suppose you have a circle with a circumference of 10 units.
To find the diameter:
1. Divide the circumference by π:
Diameter = 10 / π ≈ 3.183 units (rounded to three decimal places).
To find the radius:
2. Divide the diameter by 2:
Radius = 3.183 / 2 ≈ 1.592 units (rounded to three decimal places).
So, in this example, the diameter of the circle is approximately 3.183 units, and the radius is approximately 1.592 units.
