Determine which two values the following expression is between.

π2
a. 9 and 9.61
b. 9.61 and 10.24
c. 10.24 and 10.89

The answer is: [B]: 9.61 and 10.24 .

[Note: This is based on the assumption that the expression in the problem given is: "(π) squared"; or: "π² " — [and NOT: "(π*2)"; or, "(2*π)".]

Explanation:

Let us assume the expression in the problem means:
"(π) squared" or, "π² " {"pi squared"; or, "pi to the second power"}.

Then, π² = (3.1415926535897932) ² 
             = 9.8696044010893583772

Even if one uses "3.14" for "π" ; since π ≈ 3.14; then:
  Then, π² ≈ (3.14)² ;  and: (3.14)² = 9.8596

Both methods result is 9.8; which corresponds with:
  Answer choice: [B]: 9.61 and 10.24 .
