Circumference of a circle: 2 x pi x radius.
to find the raduis of any circle, divde the diameter by 2. in this case, the answer would be 3.50
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
The formula; 2 * Pi * Radius = circumference Will calculate the circumference of a circle.
find the radius of a circle with circumference of 42.1
Circumference of a circle: 2 x pi x radius.
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.
Circumference = 2*pi*r where pi = 3.14159 (approx) and r is the radius.
Radius (not raduis) =circumference/(2*pi)
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!

find the radius of a circle with circumference of 42.1
The circumference of a circle is the length of the circle's perimeter.
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
