@tylermcmullen23

OpenStudy (anonymous):

noo

OpenStudy (anonymous):

my bad i made a huge mistake.

OpenStudy (anonymous):

pi*r^2h is the formula

OpenStudy (anonymous):

So was I right the first time? 80 cm

OpenStudy (anonymous):

so far, 50240=3.14 (40^2) (h)

OpenStudy (anonymous):

so, 50240=5024(h)

OpenStudy (anonymous):

divide each side by 5024 to get h=10

OpenStudy (anonymous):

to make sure, plug 10 in as h in the formula so that 3.14*40^2*10

OpenStudy (anonymous):

Ok starting to kinda understand :3.......

OpenStudy (anonymous):

and yes 10 is correct!

OpenStudy (anonymous):

Oh ok thx((::

OpenStudy (anonymous):
