Question

how do i find the exact circumference of a circle with a diameter of 5 inches.

Answer 1

circumference = pi*(diameter)

where

pi = 3.14 approximately

Answer 2

since they want the exact circumference, you would leave the answer in terms of pi

example:
diameter = 10
circumference = 10*pi
this isn't the answer as it's just an example

Answer 3

ok so 5*pi ?

Answer 4

so the answer would be around 15.7?

Answer 5

the answer they want is `5pi` since they want an exact answer

Answer 6

ohh ok i see now thanks!

Answer 7

no problem
