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...
The area of circle is equal to the space occupied by the circle. It is equal to the product of the pi and square of the radius of the circle. It is expressed as follows: {eq}\rm Area\;of\;circle = \rm \pi {r^2} {/eq}...

The general form of Green's theorem is∫CF⋅dr=∬R(∂Q∂x−∂P∂y)dA By using the given circle equation we have to find the area of the circle and apply in the general form to get a solution. Answer and...
The example below is similar to one above although, since we have a semi-circle we need to calculate a fraction (one-half) of the circle’s area. Note in this example the diameter, and not the radius is shown. Example: Decisions! Combine? Subtract It is common to have more than one...
Calculate the area of a Circle in Excel The area of a circle is 3.14*(radius*radius). To create the formula in Excel, I could suggest the exponential function however, since the goal is just to find the square, we can twist the formula a little. The syntax to find the area of a ...
