They would have to give you enough information to eventually get the diameter. If they gave you the area of a circle and asked for the circumference, you can determine the radius, and from the radius the diameter, and then the circumference.
If they said "What is the circumference if the area of a circle is 36pi?"
Area of a circle is pi*r2, which would give us a value for r = 6
Diameter is 2*r, or = 12.
Circumference is d*pi, or 12pi

What is the diameter and radius of the circumference 16.956?
The diameter is (the circumference) divided by (pi) . The radius is 1/2 of the diameter.
What is the radius of a circle with a circumference 26 inches?
To find the radius of a circle with a given circumference, you can use the formula: circumference = 2 * π * radius. Given that the circumference is 26 inches, you can plug this value into the formula and solve for the radius. Dividing the circumference by 2π gives you the radius of the circle, which in this case is approximately 4.14 inches.
How do you find the area of a circle without knowing the radius?
If the circumference or diameter is given then you can find the radius or simply measure the distance from the centre of the circle to the circumference.
How do you find circumfrance using diameter?
circumference of a circle = pi*diameter or 2*pi*radius
find the length of the radius the circumference and the area of the circle the center is 20 feet use 3.14 for pi?
radius = diameter/2 circumference = 2*pi*radius or pi*diameter area = pi*radius2
