@Ilovecake @mathmath333 @piercetheveil47

OpenStudy (anonymous):

first, find half of 12.5

OpenStudy (mathmath333):

diameter is given \(12.5) find the radius first

OpenStudy (anonymous):

that's 6.25

OpenStudy (anonymous):

r = D ÷ 2r = 12.5 ÷ 2r = 6.25

OpenStudy (anonymous):

so the area is 122.72!

OpenStudy (anonymous):

okay thanks :) @pikachump

OpenStudy (anonymous):

no problem! glad I could help :)

OpenStudy (mathmath333):

formula for area is \(\huge \pi r^2\)
