is it c

OpenStudy (narissa):

or b

OpenStudy (anonymous):

This one is pretty tricky, but it's similar to the last one. All we have to do is find half of the circumference at the bottom, then add it to 26.

OpenStudy (anonymous):

Did you find the circumference to the bottom circle?

OpenStudy (narissa):

34

OpenStudy (anonymous):

We have the diameter of 8 so just multiply that by pi to get 25.13. So our circumference is 25.13.

OpenStudy (narissa):

so i have to find half of that then add 26

OpenStudy (anonymous):

Divide that by 2 to get the perimeter of the bottom section. And yes, that's what you gotta do

OpenStudy (anonymous):

25.13 divided by 2 would be 12.56. just add that to 26 to get the answer.

OpenStudy (narissa):

38.56?

OpenStudy (narissa):

thanks

OpenStudy (anonymous):

yep, 38.56
