rebeccaxhawaii (rebeccaxhawaii):
ok so the diameter is 8
rebeccaxhawaii (rebeccaxhawaii):
the circle area formula is pi x radius^2
rebeccaxhawaii (rebeccaxhawaii):
the radius is half the diameter therefore making it 4
OpenStudy (anonymous):
i got that part, i really just needed help with the second!
rebeccaxhawaii (rebeccaxhawaii):
\[3.14 * 4^{2}\]

they are talking about a circular frame right ?
OpenStudy (anonymous):
in the first or second?
rebeccaxhawaii (rebeccaxhawaii):
nvm i think they are talking about a circle
rebeccaxhawaii (rebeccaxhawaii):
so we will add 2 inches to 4 because of the width
OpenStudy (anonymous):
oh, okay!

rebeccaxhawaii (rebeccaxhawaii):
so pi x 6^2
OpenStudy (anonymous):
so the answer is 113?
rebeccaxhawaii (rebeccaxhawaii):
yes
OpenStudy (anonymous):
thats not one of the choices.. is there another step or something?
rebeccaxhawaii (rebeccaxhawaii):
\[\Pi = 3.14\] and \[6^{2}\] is 36 so it is one of your choices

OpenStudy (anonymous):
the answer to that would be 32, right?
rebeccaxhawaii (rebeccaxhawaii):
no u only need to simply 4^2 then include pi by it
