The radius of a circle equals the diameter divided by two. 30/2 is 15, so your answer is 15 cm.
The diameter of a circle is twice its radius. Thus the radius of a circle is half its diameter. → a circle with a diameter of 15 cm has a radius of 15/2 cm = 7.5 cm
The radius if the circle is half of its diameter and so 30/2 = 15 mm
It is: 15/2 = 7.5 units of measurement
If the radius is 2 then the diameter is 2*2 = 4 inches and the circumference is about 12.6 inches and not 15 inches
The radius of a circle equals the diameter divided by two. 30/2 is 15, so your answer is 15 cm.
If the diameter is 15 then the radius is 7.5.
The diameter of a circle is twice its radius. Thus the radius of a circle is half its diameter. → a circle with a diameter of 15 cm has a radius of 15/2 cm = 7.5 cm
The radius of a circle is 1/2 of its diameter. If the diameter is 15 meters, then the radius is 7.5 meters.
The length of the diameter will be 30 cm if the radius is 15 cm.
Radius is half of the diameter
Always remember: the radius is half the diameter (or the diameter is 2 times the radius). So divide 15 by 2, and you get 7.5, the radius is 7.5. Don't forget to add the unit ;)
radius = diameter/2
R=D/2. If the diameter of a circle is 18 inches, the radius is 9 inches. Radius = 1/2 diameter or 9"
The radius is 15 feet 2r=30 30/2=15 15 is the radius
30 inches. The diameter is twice the length of the radius.
Diameter is twice the radius, so 15 cm.
