12 cm A diameter is twice as long as the radius of a circle. D = 2r D = 2(6cm) = 12cm
The circumference of circle with radius 12cm is 75.4cm
The radius of a circle is the distance from the centre to the edge. The diameter is the distance right across the circle through the centre. So the diameter of a circle is always twice its radius. So if the radius of a circular CD is 6cm, the diameter is twice this - 12cm.
The circumference of a circle if the diameter is 12cm is 37.7cm
The diameter is twice the radius and so it is 24cm
the diameter of a circle is double the radius so if the radius is 12 cm then the diameter is 24 cm
12 cm A diameter is twice as long as the radius of a circle. D = 2r D = 2(6cm) = 12cm
The diameter of circle A is 12cm so its radius must be 6cm.
The circumference of circle with radius 12cm is 75.4cm
The radius of a circle is the distance from the centre to the edge. The diameter is the distance right across the circle through the centre. So the diameter of a circle is always twice its radius. So if the radius of a circular CD is 6cm, the diameter is twice this - 12cm.
The circumference of a circle if the diameter is 12cm is 37.7cm
The diameter is twice the radius and so it is 24cm
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.
The radius of a circle is half of the diameter, so the radius of a circle with a diameter of 14in is 7in.
