The diameter is twice the radius and so 2 times 16 = 32cm
16cm
It has a circumference of 50.3cm
256 pi cm2
64 pi sqcm
Using 3.14 as Pi the area of circle is: 200.96
R 16cm is to diameter
16cm
The diameter of a circle is the length of a straight line from a point on the edge of the circle passing through the center of the circle and onto a point on the opposite edge of the circle. The radius of a circle is the length of a straight line from the center of a circle to a point on the edge of the edge of the circle. So the radius of a circle is half its diameter, in this case 8cm.
It has a circumference of 50.3cm
256 pi cm2
The diameter is twice the radius. Or The Radius is half the diameter. Algebraically, d = 2r or r = d/2
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
64 pi sqcm
Using 3.14 as Pi the area of circle is: 200.96
Irrespective of the units of length, be they Metric, or Imperial , the diameter is twice the radius. Algebraically written as d = 2r o r ( d = r + r).
The radius of a circle is always half of the diameter. If the diameter is 85.4, the radius is 42.7.
The radius of a circle is half of the diameter, so the radius of a circle with a diameter of 14in is 7in.
