multiply radius by 2
Multiply by 2 ! A radius is half a diameter !
What we do is that we multiply the radius with 2 to find the diameter, and then multiply the diameter with 3.14 (pi). 73 * 2 * 3.14 = 458.44
To find the diameter of a circle you multiply the radius by 2 or d=r2
If that's the diameter, multiply the diameter by pi (which is about 3.1416). If it's the radius, multiply it by (2 x pi).

You just multiply the given radius by 2. That is diameter is just double of the radius. This is universal formula.
You measure it. If you know the radius (of a circle), you multiply it by 2 to get the diameter. If you know the circumference of a circle, you divide by pi to get the diameter.You measure it.

The radius is always one-half the diameter so multiply the radius by 2 to get the diameter.
multiply by 2
Multiply the radius by 2.
The diameter is twice the radius. So multiply the radius by 2
To find the diameter of a circle you multiply the radius by 2 or d=r2
If that's the diameter, multiply the diameter by pi (which is about 3.1416). If it's the radius, multiply it by (2 x pi).
The radius is 1/2 of the diameter, so if the radius is 20 units then the diameter is 40 units. You multiply the radius by 2 to get the diameter.
