If the area of a circle is given as 67cm squared, the diameter is 9.236 cm and the circumference is 29.02 cm
If you are given the radius of the circle, you can use the formula: diameter = 2*radius If you are given the circumference of the circle, you can use the formula: diameter = circumference/pi
Circumference equals the diameter times pi. The diameter is 2 times radius. Radius equals Circumference divided by pi then divided by 2.
Circumfrence=diameter X 3.14 (diameter=2 X radius)
Not enough information, since you don't specify ANY information about the circle.For example, if you know the diameter, the circumference is pi x diameter; if you know the radius, the circumference is 2 x pi x radius.
By using the other information supplied about the circle to calculate either its radius (from which its area can be calculated) or its area (if the circle is similar to another with a given area and some ratio between the two circle is given):If the diameter is given: radius = diameter ÷ 2If the circumference is given: radius = circumference ÷ 2πIf the circle is similar to another circle which has a given area, and the length ratio is given; square the length ratio to get the area ratio and apply to the given area.
Given a circle with a diameter of 4, the circumference is: 12.6 (diameter x Pi = circumference).
Diameter of a circle = circumference/pi
Divide the circumference by pi (about 3.1416). The result is the circle's diameter.
TTr2 [Pi r squared] finds the area of the circle. TT x d [Pi x diameter] finds the circumference of a circle]
If you are given the radius of the circle, you can use the formula: diameter = 2*radius If you are given the circumference of the circle, you can use the formula: diameter = circumference/pi
Circumference = diameter*pi
The diameter of the circle equals the circumference divided by Pi (3.14159....).
Circumference = (diameter) multiplied by (pi)
Circumference of a circle = (pi) x (diameter)
If you mean the diameter and radius of a circle given the circumference it is:- diameter = circumference/pi radius = circumference/(2*pi)
circumference of a circle = 2*pi*radius or pi*diameter
Circumference of a circle is the diameter times pi or 2pi times the radius. Given the diameter, circumference = 16 times pi. So, the circumference is 16pi or 50.265
