A circle's diameter and radius are both intimately tied to its circumference, or the distance all the way around the outside of the circle. (Circumference is just a fancy word for the perimeter of any round object). So if you know the circumference, you can calculate the circle's radius...
Sphere size is calculated using two measures: the volume (how much space the sphere takes up) and the surface area (the total area of the sphere's surface). Both sphere size and surface area can be easily calculated if you know the radius or diameter of the sphere. The formula for volu...
How to Calculate an Area Using the Equation of Continuity Step 1: Identify a spot in the pipe with a known area and calculate the area at that spot. Step 2: Identify two velocities: one at the point identified in step 1 and the other in the place where the area is desired to b...
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 ...
The following example shows how to clip an elliptical (circular) area out of a rectangle. To conceptualize this example, consider the rectangle in the illustration. A rectangle The following illustration shows an ellipse with a radius of 50 centered at the position 200, 100. An ellipse centere...
FAQ: How do you calculate the area and arc length of region ABCD using given values? What is a radian? A radian is a unit of measurement commonly used in mathematics and physics to measure angles. It is defined as the angle subtended by an arc of a circle that ha...
If we change the radius in a factor of {eq}n {/eq}, we have: {eq}A=\pi (nr)^2=n^2\pi r^2 {/eq} Using the area for the initial circle {eq}A=\pi... Learn more about this topic: Finding the Area & Circumference of a Circle ...
We display your teaching profile to students who are inside of your preferred travel area. We calculate your travel distance using Google driving directions. On average, teachers set their travel distance to 10 miles, however this distance will vary based ...
Calculating Area You can also calculate the area of a circle using the circle's radius. The area of a circle is equal to π times the radius squared. Remember that any number squared is equal to that number multiplied by itself. So area, A, can be found using the following equation: ...
