Circumference = 2*pi*radius or diameter*pi
The area of any circle = pi*radius2
22 divided by 7 will result in a number very similar to pi.
pi times radius squared. :)
Figure out its radius and multiply it by pi or 3.14.
Circumference = 2*pi*radius or diameter*pi
Figure the radius (r=C/2 pi) figure the area (A= pi x r squared). Note - the pi's don't cancel out.
i think you do d x pi
The area of any circle = pi*radius2
22 divided by 7 will result in a number very similar to pi.
d * pi or 2 * r * pi Where d is diameter and r is radius and pi = 3.14159
Use the formula for the particular figure
just remember it by 3.14 The best way to remember pi is by memorizing the sentence: "How I wish I could determine of circle round the exact relation Archimede found" The number of letters in each word of this sentence represents one figure of pi. Only the last figure (5) from the word "found" does not correspond to the correct figure of pi in its position.
How many places do you want it figured to? 3.14159 is a fairly common answer, but the value of pi is infinite.
Circumference = 2 x {pi} x radius = {pi} x diameter
No, it is not. A triangle is a two-dimensional figure whereas pi is a dimension-less number.
