Can someone please help I'm not understanding this I know the formulas but not exactly how to use them or where to start.
Please post one of the formulas and I'll show you how to use it for a specific problem.
#4 SA=LA+ 2B
#5 LA=ph(perimeter of the base * height)
#6 SA=LA+2B or 2pirh+2pir^2
#9 not sure
#10 believe is 19m
wrong ones sorry!!
Believe these are the ones
LA = ph
P = 4 * 11.2
LA = 44.8 * 20
LA = 896 sq. cm
Just took this assessment, these are all correct answers.
No, don't listen to the person above. The correct answer for #3 is D.
I'm 100% sure.
Anonymous is right, 3 is D.
Anon is Right. Those answers above are right!
