for circumference you multiply diameter by pi (22 over 7 or 3.14) and for area you do radius (half of diameter) multiplied by itself then multiplied by pi. if you want volume you can multiply the height of the cylinder by the area of it's circle.

### IF the circumference of a circle is 6.28 what is the area?

The circumference and area of a circle, with radius r is: circumference = 2*pi*r and area = pi*r2 Use the first to calculate r and then the second to calculate the area.

### How do you calculate circumference and area of pi?

Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius

### If the circumference of a circle is increased by 50 then the area will be increased by?

there is no constant that will calculate this, since circumference is calculated with only radius and area with radius squared. you will have to calculate the radius using the initial circumference and then the radius again for the new circumference (with the 50 added). then calculate an area for each radius..then you can see the increase.

### How do you you do circumference 6''?

The answer will depend on what is meant by "how do you you do" or even "how do you do". I do not do circumference. A can draw it, I can calculate it, I can calculate other measures (area, radius, diameter) from it but I do not DO it!

There is no such thing as an "area of circumference".If 27 cm is the diameter, you can calculate the circumference by multiplying this by pi, which is approximately 3.1416.

### How do you calculate the area of a circle if you know the circumference?

By dividing its circumference by 2*pi will give the radius of the circle and its area = pi*radius2

### How do you covert area into circumference?

Well, you can't really "convert" it, but I assumeyou want to calculate the circumference from the area. First, you need to know what figure you are talking about. For the specific case of a circle, I suggest you use the formula for the area of a circle, replace the known area, and solve for the radius. Once you have that, it is easy to calculate the circumference.
