First of all, 'pi' is not a formula. It's a number.
Next, the number can never be written exactly correctly with digits, no matter how far
the decimal is carried out. That's why a symbol was invented to represent it.
'3.14' is a rough approximation for 'pi'. It's about 0.05% too small.
Many people use '22/7' for 'pi'. That's about 0.04% too big.
3.142 is better.
3.1416 is even better.
3.14159 is even better.
3.1415927 is even better.
3.1416592653589792 is even better.
'Pi' is just a characteristic of the thing we call a 'circle'. There's no 'why' pi is that
number. It's like asking why water feels runny, or why air doesn't smell.

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
If the area of a circle is 314 square inches what is the circumference of the circle?
62.8 inches. the formula for a circle's area is a = pi x r squared. substitute 3.14 for pi and 314 for a. 314 = 3.14 x r squared (divide both sides by 3.14) v 100 = r squared (find the square root of both sides) v r = positive or negative 10 . since it stands for the radius of a circle, it has to be positive. now that you know the circle's radius, you can solve the circumference formula, c = 2 x pi x r. c = 2 x 3.14 x 10 c = 62.8

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
What is the diameter of a circle whose area is 314 cm square?
To find the diameter of a circle with a given area, you first need to calculate the radius using the formula for the area of a circle: A = πr^2. Given that the area is 314 cm^2, you can rearrange the formula to solve for the radius, which would be √(A/π). Plugging in the area, you get √(314/π) ≈ 10 cm. Finally, to find the diameter, you double the radius, resulting in a diameter of approximately 20 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.
