Question

the circumference of a circle is 5 pi what is the diameter?

Answer 1

\(\Large\color{blue}{ \bf C=5π }\) (this is what you are given )

\(\Large\color{blue}{ \bf C=dπ }\) (this is the formula for the circumference in terms of diameter and π )

the diameter equals to ??

Answer 2

circumference=(2)(pi)(r)
5=(2)(pi)(r)
2.5=pi(r)
2.5/pi=r
so when you do that, you will get the radius, when you get that do x2 to get the diameter.

Answer 3

dg, just read what I wrote, it is as simple as that, don't make it more complicated.
