Radius time 2 equals the diameter.
you cant: pi is the same for any circle - 3.1415... the diamter or the radius has to be given diameter divided by two equals the radius the radius times two equals the diameter
72, double the radius because radius is half of the whole diameter.
Circumference = (pi) x (diameter) Diameter = 2 x radius
The radius is half the diameter. Therefore, 770 divided by 2 equals 385mm
radius is half the length of diameter. So the radius will be 3cm. Thank you. Sharada
12 cm.
Since the diameter is always twice the length of the radius, the length of the radius is 6cm.
6/2 = a radius of 3 cm
12 cm
The radius of the circle is half the diameter of the circle. 30mm radius would mean 60mm diameter or 6cm.
The diameter of circle A is 12cm so its radius must be 6cm.
6cm
The circumference of a circle = 2*pi*radius or diameter*pi
Radius time 2 equals the diameter.
12 cm A diameter is twice as long as the radius of a circle. D = 2r D = 2(6cm) = 12cm
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.
