Answer:
Area = 270π inches squared. Volume = 550π inches cubed
Step-by-step explanation:
Surface Area:
Cylinder Area=2πrh+2πr^2= 180π+50π=230π inches squared.
Cone Area = πr(r+√(h^2+r^2)) = 5π(18) = 90π inches squared.
Total Area = 230π+90π = 320π inches squared.
Total Area - base = 320π-50π = 270π inches squared.
Volume:
Cylinder volume = πr^2h = 450π inches cubed
Cone volume = πr^2(h/3) = 100π inches cubed
Total Volume = 550π inches cubed
Yes, I believe the points are indeed correct.
