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.
diameter of a circle = 2*radius or circumference/pi
you need to quote the circumference to calculate the length of the arc or its percentage
The circumference of a circle is defined as 2(pi)d. Transpose the formula and calculate it.
Calculate the area of the circle of 101 mm radius. Multiply this by the length of 656 mm. Divide the result by 1,000.
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.
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. :)
The length around a circle is the circumference The length across a circle is the diameter
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
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 area of a circle Pi can be used to calculate the circumference of a circle
The length of an arc of a circle refers to the product of the central angle and the radius of the circle.
