Now to calculate the circumference of the circle we multiply pi (∏) by the diameter (d) of the circle. ∏ is a fixed value equal to 3.14, or to be exact 3.1415926535897932384 but = 3.14 will do for our calculations. Calculating the circumference using diameter. We now know what the dia...

Now that we can easily calculate the circumference from either diameter or radius, we can use this formula to find the perimeter of a semi circle or arc length. Arc length can be explained as simply the length of a section of the boundary around a circle. When trying to find the circumfe...
How to Calculate the Circumference of a Circle? Rapid Recall Solved Examples Frequently Asked Questions What is the Circumference of a Circle? A circle is a closed round shape where all the points on the boundary are equally spaced from a fixed point known as the center. The circumference...
To calculate circumference, then, you multiply the circle's radius by 6.28. Take a circle with a radius of 4 inches. Multiplying the radius by 6.28 give you 25.12. So the circle's circumference is 25.12 inches. Calculating Area You can also calculate the area of a circle using the circle...
How to calculate the area of a circle. It’s as easy as pi. Let’s first make sure that we understand the difference between circumference and area. The circumference of a circle is the perimeter of the circle. Imagine that the circle is straightening itself out. The leng...

You can calculate the circumference of any circle if you know either the radius or diameter. The formulas are: C = πd C = 2πr where d is the diameter of the circle, r is its radius, and π is pi. So if you measure the diameter of a circle to be 8.5 cm, you would have: ...
Calculating the area of a space is an important for everyday activities, including estimating the amount of carpet for a bedroom or landscaping a yard. The formula for calculating the area of a rectangle is slightly different from the formula used to calculate the area of a circle or triangle...
