Question

Which of the following is the smallest value?

pi/4

pi cubed

pi/8

pi squared

Answer 1

Explanation:

pi^3 is about 30. (3 * 3 * 3 get's you to 27. The 0.14 will make a bit more)

pi^2 is about 10 (3^2 = 9. You need only get an approximate answer)

pi/4 = about 0.75 I'm using 3 to be the value of pi. That's close enough to get an answer.

pi/8 = 3/8 which is about 0.375 which is the smallest one.
