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.
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
What is the diameter if the circumference is 27 cm?
Circumference = 2 x radius x pi [diameter = 2 x radius] So: Circumference = diameter x pi Diameter = Circumference / pi Diameter = 27/3.1416 Diameter = 8.60 cm
How do you find the diameter and then the circumference if you have the radius?
Diameter = radius * 2 Circumference = pi * diameter.
How can you find the diameter and the radius if the circumference is given?
Diameter = circumference/pi Radius = circumference/2*pi
How do you find the radius of a circle is you have the circumference?
pi X diameter finds the circumference so circumference divided by pi will leave the diameter. half the diameter to find the radius
How to find the radius of a circle with the circumference?
Divide circumference by pi, that gives diameter. Radius is half of diameter
How do you find the circumference if you know the radius?
Okay finding circumference from knowing the radius right? The radius is equal to half the diameter and circumference is equal to pi * diameter. So double the radius and multiply it by 3.14 then you will get the circumference!
How do you find the length of of the radius of a circle?
You can either measure it, or calculate it if you know the diameter (radius = diameter / 2), or the circumference (radius = circumference / (2pi)).
How do you find length and width given the circumference?
If you mean the diameter and radius of a circle given the circumference it is:- diameter = circumference/pi radius = circumference/(2*pi)
How do you find the diameter and circumference of a circle if the radius is 7?
Diameter = Radius*2 = 14 units. Circumference = pi*Diameter = 43.98 units.
How do you find out the circumference from the diameter?
circumference of a circle = pi*diameter or 2*pi*radius
How do you find the radius and diameter when they give you a circumference?
divide the circumference by pi ( 3.146) which will give you the diameter divide that by 2 and you have the radius
What formula do you use to find the radius diameter and circumference of a circle?
Radius is diameter divided by two. Diameter is radius times two or circumference divided by pi. Circumference is diameter times pi. Pi is roughly 3.14
How do you calculate circumference?
to calculate circumference you find a circles radius or diameter. you do diameter times pi or radius times 2 times pi. the you have circumference!
