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.

What is the area of a circle with the circumference of 62.8 inches?
Circumference = 2 pi r = 62.8 so r = 31.4/pi = 10 Area = pi r2 = 100 pi = 314 in2
What is the diameter of a circle whose circumference is 314?
The diameter of a circle whose circumference is 314 is about 1 (99.95).
What is the radius of a circle if its area is 314?
9.9975
How do you find the area of a circle that has a radius of 10?
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.
What is the nearest whatever of Pi?
pi = 3.1415926535897932384626433832795... pi to the tenths = 3.1 pi to the hundredths = 3.14 pi to the thousandths = 3.142 pi to the ten-thousandths = 3.1416 pi to the 10th decimal places = 3.1415926536 etc. ============================

Circumference of a circle with a diameter of 100 feet?
100*pi≈314 feet
How do you find the square feet of a circle with a radius of 10 feet?
314 feet²Area of a circle = pi x radius²let pi = 3.14A = 3.14 x 10²A = 3.14 x 100A = 314 feet²
What is the area of a circle with the circumference of 62.8 inches?
Circumference = 2 pi r = 62.8 so r = 31.4/pi = 10 Area = pi r2 = 100 pi = 314 in2
What is the circumference of a circle with a diameter equaling with 7 centimeters in length use 314 for pi?
If you mean 3.14 for pi then the circumference is: 7*3.14 = 21.98 cm
How do you find the radius if given the area is 314cm2?
Divide 314 by pi and square root the answer which will give you the radius.
