The diameter is twice the radius and so it is 24cm
12 cm A diameter is twice as long as the radius of a circle. D = 2r D = 2(6cm) = 12cm
Radius: 24/2 = 12 cm
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 circle with radius 12cm is 75.4cm
The circumference of a circle if the diameter is 12cm is 37.7cm
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
Radius: 24/2 = 12 cm
The diameter of circle A is 12cm so its radius must be 6cm.
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 circle with radius 12cm is 75.4cm
The circumference of a circle if the diameter is 12cm is 37.7cm
Close to 12cm
The radius of the sector with an angle of 27 degrees and arc of 12cm is: 25.46 cm
Radius in from the center of circle or sphere, so a radius of 3.8 cm is a diameter of 7.6cm and circumference 23.8 cm (or 24 cm). Or If you mean 3.8 is the diameter (width), then radius is half (1/2) which equals 1.9 cm and circumference of 11.9 cm (12cm). Or If circumference 3.8 then radius is 1.2cm and area is 1.152cm. I hope this answers your question. lofty_720@yahoo.com.au
Radius = Diameter/2 Diameter = 2* Radius
