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.
The circumference of a circle is 2*pi*radius or diameter*pi
That depends on what information is given.Area of a circle: A = pi x radius squaredSolving for radius: radius = root(A/pi)Diameter of a circle = 2 x radiusSolving for radius:radius = diameter / 2Circumference of a circle: circumference = 2 x pi x radiusSolving for radius:radius = circumference / (2 x pi)
Radius = Diameter/2 Diameter = 2* Radius
To find the diameter of a circle when given the area, we first need to calculate the radius. The formula for the area of a circle is A = πr^2, where A is the area and r is the radius. Given that the area is 56, we can rearrange the formula to solve for the radius: r = √(A/π) = √(56/π) ≈ 4.74. Finally, to find the diameter, we double the radius, so the diameter of the circle is approximately 9.48 units.

The circumference of a circle is 2*pi*radius or diameter*pi
Use the formula for the circle: area = pi x radius squared. Replace the area, and solve for the radius. Multiply the radius by 2 to get the diameter.
Solve the equation for the area of the circle (area = pi x radius2) for radius. Multiply the radius by 2 to obtain the diameter.
Use the formula for the area of a circle (A = pi x radius2). Replace the data you know (the area), and solve for radius. Then, you can double this radius to get the diameter.

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.
radius = diameter/2
The radius is half the diameter. So, if the diameter is 8, then the radius is 4.
