No, but it's a relatively close approximation. 22/7 rounded to six decimal places is 3.142857, whereas pi is 3.141593.
---- 22/7 is only correct to 2 decimal places.
A better approximation is 355/113 which is correct to 6 decimal places.
355/113 = 3.141592920353... π = 3.141592653589793...
If you need to do accurate calculations involving pi you should use the π (pi) key on a calculator.
22/pi is approximately 7.0028175
pi = 22/7
Firstly, it is pi, not phi. Second, 22/7 is a ratio of 2 integers. It is, therefore a rational number. pi is not a rational number, so it cannot be 22/7. It is a near enough approximation, though.
If 22 feet is the radius then area is pi x 22 x 22 square feet where pi = 3.1415 If 22 feet is the diameter then area is pi x11 x 11 square feet where pi = 3.1415
No. But it's very convenient, and so close to 'pi' that it's often perfectly good enough for the purpose. In fact, it's amazing how close (22/7) really is ... it's larger than 'pi' by only about 0.04 percent !
No. 22/7 is a close approximation. pi is an irrational number so there is no ratio of integers that will equal pi.
Using 3.14 as Pi the area of circle is: 0
No, 22 over 7 is not equal to pi, but is instead an approximation of pi, as it only gives you 3 digits of pi, the rest (after 3.14) in 22/7 are wrong. Pi is 3.141926......... And goes on forever, meaning that a fraction such as 22/7 will never be fully equivalent to pi.
22 x 22 x pi, ie 484 pi sqft.
While there is no fraction form for pi, 22/7 is an approximation of pi that can be used for a rough calculation .
PI rocks can you find area of circle or sector without pi ? pi = 22 /7 = 3.1415923535.... Pi is the Base for all surface areas in the world. so dont forget pi = 22 /7
Here are some facts and figures about pi. Pi (as a decimal) = 3.14 Pi (as a fraction) = 22/7
