Did you learn a formula for the circumference?

2. Astrophysics

$C = 2 \pi r$

3. anonymous

yea of course i just forgot and i cant look at anything but i think its C=2pr

4. Astrophysics

Plug and chug

5. Astrophysics

Yup, that's right :)

6. anonymous

yea ig i do know it

7. Astrophysics

8. lochana

yes that's right. So plug in. :)

9. anonymous

so multiply 3.5 x 3.14

10. Astrophysics

Yup, don't forget to multiply by 2

11. Astrophysics

Because the formula is C = 2 pi r

12. lochana

You will get 21.98. Ans A

13. anonymous

yes so

14. anonymous

A

15. Astrophysics

Sounds good!
