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. 22/7 is a close approximation. pi is an irrational number so there is no ratio of integers that will equal pi.
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 !
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
3.141592653589793 + 22 = 25.14159
