you'll have to start by measuring its radius or diameter in feet. Here's why: you need that linear (or straight line) measurement in order to calculate the circle's area.
Calculating the circumference using the radius. If we have the radius of a circle then to calculate the circumference we multiply pi (∏) by the radius (r) of a circle and then multiply by 2. For the circle above we have a radius (r) of 5cm, so lets calculate the circumference: And...
A circle is a two-dimensional object, which means that area is measured in units squared, such as square inches or square centimeters. To find the area of the circle, you only need to know the radius. The radius is the distance from the center of the circle to any point on the circle...
In order to calculate the perimeter of a circle, you must first remember the formula to calculate the circumference of a circle. Well, the formula is not difficult to remember, it's2*PI*R, where PI is a well-known Mathematics constant and R is the radius of the circle. You can get ...
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 ...
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...

Draw a perfect square around the circle. Step 3 Calculate the area of the square, and divide that by the surface area of the facing-out side of a brick. This method yields a ceiling estimate of the number of bricks you will need. You are not making allowances for the space needed for...

A chord is a straight line that connects two points on the circumference of the circle without passing through the center. If the line passes through the center of the circle, it is a diameter. To calculate the chord length, you need to know the radius and either the central angle or th...
