Question

Which of the following expressions have a value between 7 and 8?

A) √50
B) 2π
C) √40
D) √60
E) π^2

Answer 1

The expression that has a value between 7 and 8 is B) 2π.

Step-by-step explanation:

The expression that has a value between 7 and 8 is B) 2π.

To determine this, we can roughly estimate the value of each expression:

• √50 ≈ 7.07
• 2π ≈ 6.28
• √40 ≈ 6.32
• √60 ≈ 7.75
• π² ≈ 9.87

Among these options, only 2π has a value between 7 and 8. Therefore, the correct answer is B) 2π.
