Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
to calculate circumference you find a circles radius or diameter. you do diameter times pi or radius times 2 times pi. the you have circumference!
Because of the radius of the circle
Pi = circumference/diameter
pi*radius2 = area radius = square root of (area/pi) circumference = 2*pi*radius
Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
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
to calculate circumference you find a circles radius or diameter. you do diameter times pi or radius times 2 times pi. the you have circumference!
Because of the radius of the circle
Because the ratio of the circumference to the diameter of every circle is pi. So circumference = pi*diameter.
Pi = circumference/diameter
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.
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 pi to calculate the area or circumference of a circle
Approx. circumference = multiply diameter by 22 and divide the product by 7. Exact circumference = Pi x diameter.
Circumference of a circle = 2*pi*radius or pi*diameter. 2*pi*2.250 = 14.13716694 metres.
pi*radius2 = area radius = square root of (area/pi) circumference = 2*pi*radius
