The length of a radius is half the length of a diameter.
About 3 centimeters (1.18 inches) in diameter... Radius 15mm Circumference of 9.42 cm, or 94.2 mm
You have to use your math is this question. First you have to put in all your number in the math equation once you get your value divide that by the diameter of the light bulb to the diameter of the actual object.
how many cm in 1 inch
depends upon the thickness. I have heard of 1 mil diameter wire. Using this: density of Pt is 21.45  g/cm3 1g has a volume of 0.0466 cm3 volume is cross sectional area x length 1 mil is 0.00254 cm, radius is 0.00127, area is 5.067E-6 divide volume by cross sectional area to get length, L = 9,197 cm or 92 meters
There is no such unit of measurement as a diameter. A diameter is the distance across something - which can be as big or as small as desired.
The length of the diameter will be 30 cm if the radius is 15 cm.
Since the diameter is always twice the length of the radius, the length of the radius is 6cm.
The radius of the cylinder would be 0.64cm ! The radius is half the diameter - length has nothing to do with the question !
14 cm
It is 73 cm.
26 cm
12 cm
12 cm
It is the diameter which is twice the radius giving a length of 8 cm
The radius of a sphere with antipodes 8 cm apart is 4 cm. The distance between the antipodes of a sphere is the diameter of the sphere. The radius is half the length of the diameter.
diameter = radius × 2 → radius = diameter ÷ 2 = 10 cm ÷ 2 = 5 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
