Circumference is the total distance around a circle. It's the length of the perimeter.
The radius of a circle is half the circle's diameter
the radius of a circle is r
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
The diameter of a circle is twice its radius
Circumference is (pi x diameter of circle). (Diameter is the distance across the circle, going through the very centre. It is also twice the radius, which is the distance from the middle of the circle to the outer edge). In the question you don't indicate what the 14cm is (i.e. diameter/radius ?), so I can't work it out for you.
Circumference is the total distance around a circle. It's the length of the perimeter.
The radius of the circle.
Its diameter in feet is: 30/pi
The radius of a circle is half the circle's diameter
the radius of a circle is r
Radius of a circle= Perimeter of the circle/2*pi Radius is half the diameter Radius is the length of a straight line from the center point of the circle to the edge of the circle.
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
The diameter of a circle is twice its radius
The radius of a circle is halve the circle's diameter.
It is the radius of the circle.
The radius of a circle = the diameter of the circle divided by 2
