Yes.
R=D/2. If the diameter of a circle is 18 inches, the radius is 9 inches. Radius = 1/2 diameter or 9"
It is: (15+18)+12 = 45
False because it is the other way around in that if the diameter is 18 yards then the radius is 18/2 equals 9 yards.
If the diameter of a circle is 18 inches then its radius is 18/2 = 9 inches
18/(2*pi) = a radius of about 113.09
The volume of a sphere with a radius of 18 is about 24,429 units3
are you being serious, if you are no, 15 is not heavier than 18 pounds of feathers.
Get someone 18 or older to get it for you.
less than
radius = 18/2 = 9 cm
The two that have a circumference of 18 pie are a radius of 9 units and a diameter of 18 units.
The radius of a circle is always half of the diameter. Therefore, if the diameter of a circle is 36 units, the radius would be half of 36, which is 18 units. The formula for finding the radius from the diameter is radius = diameter / 2. So, in this case, the radius would be 18 units.
