The formula for the area of a circle is: area = pi x radius2. The radius is half the diameter.
If you know the radius, the diameter is 2R If you know the circumference, the diameter is C/R If you know the area ,the diameter is 4A/pi (pi=3.142)
The circumference of a circle is the product of pi and the diameter. If d represents the diameter, d X pi = 50 cm or d = 50/pi = 16, to the justified number of significant digits.
Surface area of a cylinder (the column) = pi*diameter*height and measured in square units.
You didn't specify what figure you are talking about. Assuming a circle: divide the diameter by 2 to get the radius. Then use the well-known formula area = pi x radius2.You didn't specify what figure you are talking about. Assuming a circle: divide the diameter by 2 to get the radius.

To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
Diameter = 2 × Radius = 2 × 8.7 cm = 17.4 cm diameter of the circle is 17.4 cm.
Infinitely many. Every diameter is a line of symmetry.

Three choices, depending on what information you have about the circle: -- Multiply the radius by itself, then multiply the result by (3.1416). -- Multiply the diameter by itself, then multiply the result by (0.7854). -- Multiply the circumference by itself, then multiply the result by (.07958).
The perimeter of such an equilateral hexagon is 54. The circumference of the largest cricle that can be inscribed in it is 18 pi. Hope that helps! That was if you meant the diameter as the length of the longest line that fits in the shape.
Circumference = 20 pi so radius = 10 so area = 100 pi squnits
Sometimes because a sphere which is a 3d figure has a diameter
