The radius is half the diameter.
The radius of a circle is half of the diameter, so if the diameter is 56cm the radius can only be 28cm.
Easy. First, double the radius to get the diameter. Next, multiply the diameter by Pi (about 3.1416) to determine the circumference.
Multipy by 2 for the diameter
Radius = Diameter/2 Diameter = 2* Radius
The radius is half the diameter.
The formula to determine speed is speed = distance / time. To determine the diameter of a circle, the formula is diameter = 2 x radius.
The radius of a circle is half of the diameter, so if the diameter is 56cm the radius can only be 28cm.
No, only if the diameter is bigger than the radius is the radius smaller than the diameter.
Well,there is only one from each.The radius is the half of the diameter,e.g if the diameter is 4 the radius is 2
The radius is half the diameter, so just divide the diameter by 2.
Easy. First, double the radius to get the diameter. Next, multiply the diameter by Pi (about 3.1416) to determine the circumference.
Multipy by 2 for the diameter
If you know the radius, then Diameter = 2 x (radius) Circumference = (pi) x (diameter) or Circumference = 2 x (pi) x (radius)
The answer depends on what information you are given. If you know the circumference, then divide by Pi and that is the diameter. Half of the diameter is the radius. If you don't know anything about the circle, you would need to measure and find the diameter.
Radius = Diameter/2 Diameter = 2* Radius
Easy. If you only have the circumference, divide it by Pi (about 3.1416). This gives you the diameter. Next, divide the diameter by two to get the radius.
