You do that by using the information you're given, combined with the facts you know
about a circle. Unfortunately, you haven't described either of those categories in your
question.
Probably the most important fact you'll need to know about a circle ... the one that
this test-question is designed to check you on ... is the formula for the circumference
of a circle:
Circumference = (pi) times (diameter).
We're noticing that you don't know that formula, and you're still calling the circumference
of a circle the "length", so we want to suggest that you make an appointment with your
teacher to get together, and review a few things that you're still not sure of.

A line segment that connects the center of a circle to a point on the circle?
what about such a line segment? the length of such a segment is called the radius. the area of the circle is pi*the length of this segment squared the circumference is 2*pi*the length of this segment
How do you find the radius given the chord length?
If you are given a chord length of a circle, unless you are given more information about the chord, you can not determine what the radius of the circle will be. This is because the chord length in a circle can vary from a length of (essentially) 0, up to a length of double the radius (the diameter). The best you can say about the radius if given the chord length, is that the length of the radius is at least as long has half half the chord length.
If the circumference of a circle is 45 cm what is the length of the diameter in centimeters?
If the circumference of a circle is 45 cm the length of the diameter in centimeters is: about 14.32 cm
Why do we use pi?
We use it to calculate the circumference of a circle.
What is an example of a radius in math?
A radius is a line drawn from the centre of a circle to the edge of that circle. It is half the length of the diameter of the circle.
How do you calculate length of a circle?
not sure There are two main lengths that are pertinent to a circle, namely, the diameter of the circle and its circumference, the phrase "length of a circle" does not convey much meaning.
How do you calculate the code length of a circle?
I never heard of a "code length"; please clarify.
How do you calculate diamater with width and length?
diameter of a circle = 2*radius or circumference/pi
What is 45 percent of a circle?
you need to quote the circumference to calculate the length of the arc or its percentage
If I have a length of Eighty meters when formed into a circle what is its diameter?
The circumference of a circle is defined as 2(pi)d. Transpose the formula and calculate it.
How do you calculate the volume in liters of a cylinder radius 101millimeter length 656 millimeter?
Calculate the area of the circle of 101 mm radius. Multiply this by the length of 656 mm. Divide the result by 1,000.
How do you calculate the length of a diameter?
length(L) of the diameter is called as the circumference........... L=∏*D.........where ∏ is 'pi' and equivalent to 22/7. and 'D' is the diameter of the circle.
How do you know circumference?
The circumference is the perimeter of a circle, total outer length of a circle. Use 2 x (pi) x r to calculate the circumference, where (pi)= 3.142, r= radius of circle. :)
What is the length of a circle known as?
The length around a circle is the circumference The length across a circle is the diameter
How do you calculate the radius from the circumference?
Of a circle: divide the length of the circumference by the value of Pi (about 3.14159). The answer is the diameter. Half of the diameter is the radius
How do you calculate circle diameter?
The answer depends on what information about the circle is given: area, radius, length and angle of arc, area and angle of sector, etc. In each case, there is a different way to calculate the diameter but, since there is no information on what is known, it is not possible to answer the question.
Pi can be used to calculate the blank of a circle?
Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
