To find the area of a circle, you multiply the radius by itself [squared] and then you multiply their product by pi.
To find the diameter of circle, you can a)Multiply the radius by two b) Divide the area by pi, find the square root of that product and then multiply it by two.

How do you figure the area of a circle if you know the diameter?
The formula for the area of a circle is: area = pi x radius2. The radius is half the diameter.
How do you figure diameter of circle?
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)
What is the diameter of a cricle when the circumfrance is 50cm?
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.
How do you figure the area of a column?
Surface area of a cylinder (the column) = pi*diameter*height and measured in square units.
How can you calculate the surface area of a diameter?
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.

How do I figure the area of a circle by diameter?
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
How many lines of symmetry does a cricle have?
Infinitely many. Every diameter is a line of symmetry.

How do you find the area of a cricle?
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).
What is circumference of a hexagon that is 18' diameter?
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.
If the circumference of a cricle is 62.8 what is the area?
Circumference = 20 pi so radius = 10 so area = 100 pi squnits
Does a 3d figure have a diameter?
Sometimes because a sphere which is a 3d figure has a diameter
What is Pi r squared is it the area of a circle?
Yes, it is. Hint, always remember to check that the figure given in the problem is the radius., and not the diameter. If it is the diameter, then the radius is half that.
