Square foot of a circle?
To find the area of a circle, either the diameter or the circumference must be known. The formula for the area from the diameter is (pi)*(1/2 of diameter) squared. From the circumference, simply substitute (circumference / pi) for diameter.
How do you calculate circumference in inches?
Circumference of a circle in inches = 2*radius*pi or diameter*pi Both radius and diameter must be in inches
What is the circumference of a circle if a circle has a radius of 226.08 dm and a diameter of 36dm?
The question does not make sense as you have made an error with the measurements. The diameter is equal to exactly twice the radius. This must always be true in any circle. Your measurements do not agree and thus they are wrong and this question can't be answered with confidence.
Can the diameter of a circle pass through the center of a circle?
A diameter of a circle must pass through the center of that circle. A cord is a line segment that has its endpoints on the circumference of a circle. It can be any line segment. If that cord also passes through the center of the circle, it is said to be a diameter of that circle. A diameter of a circle is the longest cord of the circle.
How you answer circumference?
1) First, Measure the Diameter. The diameter is the distance across a circle. It can be be seen as cutting a circle in half. 2) When the diameter is too large to determine, estimate the radius. The radius can be seen as half of the diameter. Once you picture the radius, multiply it by 2. 3) Now you may find the Circumference. Once you find the Diameter of a circle, you multiply it by pi. Pi is the value of 3.14 . Once you multiply the Diameter by pi, you find the Circumference! For example, if a jogger estimated diameter of a circular path as 200 meters across, then circumference would be 200 times 3.14 . 4) Make sure to verify your units of measurement. If your Diameter is in meters, your circumference must be in meters also. You just found the Circumference of a circle!!!
What must you do to obtain pi?
For any circle its circumference divided by its diameter is always equal to pi.

What is the circle circumference formula?
In order to calculate the circumference of a circle one must use a specific formula. The mathematical formula is C = D x 3.14. This translates to the circumference being equal to the diameter multiplied by 3.14, which is the equivalent to pi.
How do you calculate circumference in inches?
Circumference of a circle in inches = 2*radius*pi or diameter*pi Both radius and diameter must be in inches
What is the relationship called when a diameter and a circumference equal 3.14?
An impossibility because if the diameter is 3.14 then the circumference must be 3.14*pi
How do you find the radius of a circle if you know the diameter?
If you know the diameter of a circle you simply divide the diameter by 2 to get the radius. This is because the diameter is twice the length of the radius. For example, if the diameter is 10 divide by two which will give you the answer of 5 for the radius. Half it because: diameter/2 = radiusTo answer your question you must have a certin diameter. You must go 2pie times your diameterThe perimeter of a circle is called the circumference. The circumference is the distance around the circle.The circumference, C, of a circle is given by the formulawhere r is the radius of the circleA radius is half the diameter
What is a good approximation for the number that you must multiply the diameter by to get the circumference of a circle?
3 or 3.142

What is a area of a circle?
You must find the circumference. First measure a line through the cirle. Then that is the diameter then multiply the diameter by 3.14 then you have the area! Hope that helped!
What is the circumference of a 12 foot circle?
The equation for the circumference of a circle is Pi x D (Pi multiplied by the diameter). So, if you mean the circle has a diameter of 12 feet, then we must multiply 12 by Pi. (Pi is approximately 3.14) So the circumference is 12 x 3.14 = 37.68 feet, or a bit over 37' 8".
