## anonymous 5 years ago Can someone explain pi to me?

1. anonymous

In what context? ... value? relation? geometric?

2. anonymous

In geometric.

3. anonymous

Sorry forgot that important info

4. anonymous

It's kind of a magic number... and the symbol (pi $\pi$) is just used as shorthand so we don't have to keep writing out 3.1415... blah blah blah. Are you working on area of a circle or what? (which class/level are you taking?)

5. anonymous

I am working on diameter of a circle

6. anonymous

A round patio is 14 m in diameter. What is the distance around the patio?

7. anonymous

Diameter = 2 * radius... and Area = 2pi*r$Area = 2 \pi r^2$ Which info do you have that they gave you?

8. anonymous

With the formula you gave me i figured it is 43.96

9. anonymous

Ah! Ok.

10. anonymous

You want circumference (distance around)

11. anonymous

Thank you so much! I understand now. :)

12. anonymous

Cool! :) and yeah, I think you're answer is correct. :)

13. anonymous
