Question

Which of these show the numbers pi, square root of 8, and 3.5 in the correct order

a) 3.5, √8, π
b) π, √8, 3.5
c) √8, 3.5, π
d) 3.5, π, √8

Answer 1

The correct order of the numbers from least to greatest is pi (approximately 3.14159), the square root of 8 (approximately 2.8284), and 3.5. Therefore, the correct answer is option (b) π, √8, 3.5.

Step-by-step explanation:

To determine the correct order of the numbers pi (π), the square root of 8 (√8), and 3.5, we need to approximate their values:

• π is a mathematical constant, approximately equal to 3.14159.
• The square root of 8 is about 2.8284, since 2.8284² is roughly 8.
• 3.5 is already given as a decimal.

Putting these numbers in ascending order, we have π (3.14159), √8 (2.8284), and 3.5.

Therefore, the correct order is: π, √8, 3.5, which corresponds to choice (b).

Remember, it's often useful to work with an approximate value of π when exact precision is not necessary, especially in quick calculations or when working with significant figures.
