ok for the prism first,, SA = 2(LW+HL+HW) ..... L= LENGTH, H=HEIGHT, W=WIDTH
FOR THE CYLINDER SA=2piR^2+2PiRH ....pi=3.1416 , r=radius h=height of cylinder
OpenStudy (anonymous):
#8 would be b
#9 would be a
OpenStudy (anonymous):
did you try solving it first?
OpenStudy (anonymous):
no
OpenStudy (anonymous):
for the cylinder the surface area would be 471
Still Need Help?
