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).

Multiply by 2 ! A radius is half a diameter !
You just multiply the given radius by 2. That is diameter is just double of the radius. This is universal formula.
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
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.
