Hello

OpenStudy (mahmood786123):

i WILL GUIDE YOU TO THE ANSWER

OpenStudy (ashsmashum1290):

okay well what do i do first

OpenStudy (mahmood786123):

So whats the circumferance of the circle

OpenStudy (ashsmashum1290):

42

OpenStudy (mahmood786123):

what number is pi

OpenStudy (ashsmashum1290):

it doesn't show:(

OpenStudy (mahmood786123):

3.14159265359

OpenStudy (studygurl14):

pi = approx 3.14

OpenStudy (mahmood786123):

and whats the diameter of the circle

OpenStudy (studygurl14):

You have diameter (42) and pi, so just multiply them together, and you'll get circumference

OpenStudy (mahmood786123):

Study gurl just said it in a shorter way

OpenStudy (mahmood786123):

so do 42 times Pi

OpenStudy (mahmood786123):

42 x pi

OpenStudy (ashsmashum1290):

so 42x3.14=131.88

OpenStudy (studygurl14):

yep. Round that to the nearest whole number, and that's your answer

OpenStudy (mahmood786123):

132

OpenStudy (mahmood786123):
