How to calculate the area of a circle? Well then watch this video. witch is π r 2
Say you're trying to calculate the area of a circle with a radius of 3 inches. You would multiply 3 times 3 to get 9, and multiply 9 times π. Remember that π is equal to 3.14. Also note that when you multiply inches by inches, you get square inches, which is a measurement of ...
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...
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...
Calculate the area. Using the above example, we can calculate the area of a circle with a 9-inch radius. First, plug in the information:
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 ...
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 ...
