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)
How do you figure the area of a column?
Surface area of a cylinder (the column) = pi*diameter*height and measured in square units.
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 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.
