jimthompson5910 (jim_thompson5910):

You used this formula right? \[\Large V = \pi*r^2*h\]

OpenStudy (anonymous):

yes

jimthompson5910 (jim_thompson5910):

r = 6.1 and h = 1.8

jimthompson5910 (jim_thompson5910):

ignore the pi portion, what is r^2*h equal to?

OpenStudy (anonymous):

12.2

jimthompson5910 (jim_thompson5910):

r^2*h = (6.1)^2*(1.8) = ??

OpenStudy (anonymous):

no 36.6

jimthompson5910 (jim_thompson5910):

(6.1)^2 is NOT equal to 12.2

jimthompson5910 (jim_thompson5910):

(6.1)^2 = 6.1*6.1 = 37.21

OpenStudy (anonymous):

ooohh

OpenStudy (anonymous):

so x that by 1.8?

jimthompson5910 (jim_thompson5910):

If you want to say "6.1 times 2", you'd write "6.1*2"

jimthompson5910 (jim_thompson5910):

correct

OpenStudy (anonymous):

66.978

jimthompson5910 (jim_thompson5910):

yes

OpenStudy (chunkymonkay):

correct!

jimthompson5910 (jim_thompson5910):

So the volume is \[\Large 66.978\pi\]

OpenStudy (chunkymonkay):

OpenStudy (anonymous):
