Solution :-
The number 'π' is a mathematical constant. It is the ratio of a circle's circumference to its diameter. Its approximated value is 3.14. It has been represented by the Greek letter 'π' since the mid-eighteenth century, though it is also sometimes spelled out as 'pi'. Pi is an irrational number, so it cannot be expressed exactly as a fraction.
Now, here is the answer to your question.
The value of π is 3.14 (given)
Value of π²
⇒ (3.14)²
⇒ 3.14*3.14
⇒ 9.8596 or 9.86 (approx)
So, the approximated value of π² is 9.86.
