pi is an irrational number often used is geometry is formulas for area, surface area, and volume. Diameter X pi = Circumfrence is an example of an formula that uses pi.
Not only geometry involving circles. It occurs in harmonic-motion calculations such as the time of swing of a pendulum, or other oscillation. It is therefore vital in the study and use of wave-forms: sound, vibration, alternating-current electricity, the electromagnetic spectrum, etc.
Circumference = 2 pi r = 62.8 so r = 31.4/pi = 10 Area = pi r2 = 100 pi = 314 in2
The diameter of a circle whose circumference is 314 is about 1 (99.95).
Well, since the formula for the area of a circle is Pi (3.14) times the radius squared, you can use substitution to get an equation that looks like this: 3.14(102) ...which can be simplified to 3.14(100), which can be simplified to come up with the answer of 314 square units.

Diameter = 314/pi feet
Larry Shaw made pi day on 3, 14, 1989.
100*pi≈314 feet
314 feet²Area of a circle = pi x radius²let pi = 3.14A = 3.14 x 10²A = 3.14 x 100A = 314 feet²
Circumference = 2 pi r = 62.8 so r = 31.4/pi = 10 Area = pi r2 = 100 pi = 314 in2
If you mean 3.14 for pi then the circumference is: 7*3.14 = 21.98 cm
Divide 314 by pi and square root the answer which will give you the radius.
It is: the square root of (314/pi) = 9.997 units to 3 dp
A= pi r squared 3.14 * 10 *10 = 314 square feet.
(12 x "pi" x 20) + 2(36 x "pi") which equals 314 x "pi" which equals about 985.96 when pi is 3.14
Using 3.14 as Pi the area of circle is: 314.0
