To find circumference you must multiply twice the radius by π, or using the diameter, if it gives it to you, multiply that by π.
circumference = diameter x pi (pi = 3.14159265 or 3.14 for rough approximation)
You must use the information that you do have about that cicle, along with theequations and formulas you've learned that give the relationship between thekind of information you have and the radius of cicles in general.
Pi X D = Circumference. To find Diamater if you know Circumference, divide Circumference by Pi (3.14).
The circumference is: 32.1
Circumference = Pi * diameter
Known as the Circumference
circumference = diameter x pi (pi = 3.14159265 or 3.14 for rough approximation)
Yes, and it is really called the Circumference when talking about a circle
Perimeter is another word for 'Circumference'. The equation to find the circumference is C = 2pir or C = pi*d Where d = 2r & r = radius d = diameter pi = 3.141592..... ~ 3.14
Circumference of a circle is given by 2πr. So, circumference = 2 x 3.14 x 4 =25.12
12.5 km
the perimeter of a circle, also known as the circumference, is calculated by diameter multiplied by pi. Alternatively : 2 x radius x pi
You must use the information that you do have about that cicle, along with theequations and formulas you've learned that give the relationship between thekind of information you have and the radius of cicles in general.
The formula; 2 * Pi * Radius = circumference Will calculate the circumference of a circle.
Pi X D = Circumference. To find Diamater if you know Circumference, divide Circumference by Pi (3.14).
Diameter = Circumference/pi
Circumference = π * Diameter
