Assuming you mean a circle, use the formula for the area of a circle, which is usually expressed in terms of the radius, and solve for the radius. Then you can multiply that by two to get the diameter, since the diameter is twice the radius.
In basic terms...no. A diameter only applies to circles or spheres. The diameter is the distance across the middle at the widest point and the radius is half of the diameter.
Radius = Diameter/2 Diameter = 2* Radius
A radius is one half of a diameter so divide by two to get from a diameter to a radius. Or you can multiply the radius by 2 to get to the diameter.
The area of a circle is πr^2 where r is the radius and in terms of diameter it is πD where D is your diameter.

pi = circumference/diameter circumference = pi*diameter or 2*pi*radius
Radius = Diameter/2 Diameter = 2* Radius
to get the diameter from the radius you simply multiply the radius by 2 since the radius is half the diameter. d=2r where d = diameter and r = radius
A radius is one half of a diameter so divide by two to get from a diameter to a radius. Or you can multiply the radius by 2 to get to the diameter.
The length of a radius is not the length of a diameter. The diameter is two times the length of the radius.
The area of a circle is πr^2 where r is the radius and in terms of diameter it is πD where D is your diameter.
radius = diameter/2
The radius is half the diameter. So, if the diameter is 8, then the radius is 4.
A radius is half of a diameter. Example Diameter:4 Radius:2
