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.

There is no formula for Pi, it cannot be represented by any formula. It is a fundamental constant.


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 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.
