The diameter is 28cm
The circumference of a circle with a diameter of 14cm is: 43.98 cm
The radius of a circle is half of its diameter
1/2 of the diameter
The diameter of a circle is twice its radius. Thus the radius of a circle is half its diameter. → a circle with a diameter of 15 cm has a radius of 15/2 cm = 7.5 cm
The diameter is 28cm
Assuming that "it" refers to diameter, the radius is 7 cm and the circumference is 44.0 cm.
The circumference of a circle with a diameter of 14cm is: 43.98 cm
C=2 pi R
Circumference = 2*pi*radius or pi*diameter Circumference = 87.9645943 or 88 cm to the nearest cm
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.
The perimeter of a circle is equal to pi times the diameter, so for a circle with a diameter of 14 cm, multiply by pi, which is approximately 3.14, and you get 43.96 cm, which for most purposes you could round off to 44 cm.
The radius is: 6.267 cm
The diameter of a circle is twice its radius
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 always half of the diameter. If the diameter is 85.4, the radius is 42.7.
