15 (r = d/2)
Diameter = Radius*2 = 30 cm.
15mm
The radius is 15 feet 2r=30 30/2=15 15 is the radius
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 radius of the circle is half the diameter of the circle. 30mm radius would mean 60mm diameter or 6cm.
15mm. diameter is twice the radius
Radius = 1/2 of the diameter = 30
Diameter = Radius*2 = 30 cm.
The radius if the circle is half of its diameter and so 30/2 = 15 mm
the diameter of a circle that is 60 is 60 radius is 30 the circumference is 188.46
Radius = 1/2 of the diameter = 30 units
The radius of a circle equals the diameter divided by two. 30/2 is 15, so your answer is 15 cm.
30 inches; the radius of a circle is 1/2 its diameter.
15mm
The radius is 15 feet 2r=30 30/2=15 15 is the radius
6cm
