Please post one of the formulas and I'll show you how to use it for a specific problem.

Okay
#4 SA=LA+ 2B
#5 LA=ph(perimeter of the base * height)
SA=LA+ 2B
#6 SA=LA+2B or 2pirh+2pir^2
#8 SA=LA+B
#9 not sure
#10 believe is 19m

wrong ones sorry!!
1) LA=ph
SA=LA+2B
2) LA=pirl
SA+LA+B
3) LA=1/2pl
4) LA=pirl
SA=LA+B
5) SA+LA+B
Believe these are the ones

1)
LA = ph
P = 4 * 11.2
LA = 44.8 * 20
LA = 896 sq. cm
