The circumference is 2*pi*radius (not raduis) and this formula is applicable whether the radius is an integer, a fraction, or even an irrational number.
Radius = circumference/pi
Circumference of a circle: 2 x pi x radius.
Radius (not raduis) =circumference/(2*pi)
Circumference = 2*pi*r where pi = 3.14159 (approx) and r is the radius.
The perimeter of a circle is called the circumferenceTo find the circumference of a circle you do 2 times pi times radiusC = 2 * 3.14159 * 7 = 43.98inchesSince this is a half circle you have to take half of the circumference...you answer is 21.99inches
to find the raduis of any circle, divde the diameter by 2. in this case, the answer would be 3.50
You cannot.A circle has no mass nor volume and so the concept of density is not appropriate.Also, the word is radius, not raduis!
The formula; 2 * Pi * Radius = circumference Will calculate the circumference of a circle.
the fraction of the circle covered by the arc
The circumference is 2*pi*radius. It does not matter if the radius is an integer or a fraction.The circumference is 2*pi*radius.

find the radius of a circle with circumference of 42.1
If you know the circumference of a circle, you can find the radius by dividing the circumference by the value of Pi (3.14159...)
Diameter of a circle = circumference/pi
When the shape is a circle, then the perimeter is called"circumference".The circumference IS the perimeter of a circle.
Divide the known circumference by pi to find the diameter of the circle.
to find the circumference of any circle, times the diameter(d) by pi and you will get the answers.
To find the circumference of a circle in rhombus you eat SH*t .
The Circumference of a circle is twice the Radius x Pi (π) OR C = π x 2R ... (2 x Radius) x Pi (π) = Circumference The value of π is taken to be 3.142
The radius of a circle is the distance from its centre to its circumference. If a circle has a radius of r units then the length of its circumference is 2*pi*r units.
Use the information you have to find it. -- divide the length of the arc by the total circumference of the circle, or -- divide the central angle of the arc by 360 degrees (a full circle)
a circle with circumference of 25.56 inches.
Circumference of a circle = 2*pi*radius or diameter*pi
The entire circumference has a central angle of 360 degrees. The arc is a fraction of the circumference. The fraction is (central angle) divided by (360). So the arc length is: (circumference) x (central angle) / (360) .
The circumference of a circle is the length of the circle's perimeter.
