C program on how to calculate circumference of a circle? The formula; 2 * Pi * Radius = circumference Will calculate the circumference of a circle.
how do you calculate the circunference of hemisphere?
To calculate circumference you find a circles radius or diameter. you do diameter times pi or radius times 2 times pi. Then you get the circumference.
pi times diameter = circumference
The answer will depend on what is meant by "how do you you do" or even "how do you do". I do not do circumference. A can draw it, I can calculate it, I can calculate other measures (area, radius, diameter) from it but I do not DO it!
Circumference = 2*pi*radius
Circumference = diameter*pi
To calculate circumference you find a circle's radius or diameter. You do diameter times pi or radius times 2 times pi. Then you have circumference!Read more: How_do_you_calculate_circumference
You use a protractor.
The wheel (not the tire) has a circumference of pi × 12 inches. Whoops, the question changed. The original question asked what the circumference of a 12 inch wheel is... To calculate the circumference you take pi × diameter or pi × radius × 2.
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
