No, because pi is not a rational number.
A popular approximation is 22/7 = 3.14(2857....), correct to 2 decimal places.
Of particular interest is another ratio: 355/113 = 3.141592(9204...) which is correct to 6 dp. This is a rare example where remembering the 6 digits of the ratio gives pi to as many dp. Not only that, the sequence of digits, going from the denominator to the numerator make it quite an easy ratio to remember.

pi is an irrational number. It can not be expressed as a ratio of two integers.
Because it can't be expressed as a fraction
A number which can not be expressed as a ratio of two integers is "irrational". Irrational numbers can not be expressed on paper through conventional means. Examples of irrational numbers are: pi Euler's number (e) Any square root of an integer which isn't a perfect square.
pi is an irrational number because it cannot be expressed as a ratio of two integers. In fact, it is a transcendental number, but that is not relevant here. 3.14 is a rational approximation to pi. It is not equal to pi.
