Answer:
12. Diagonal=40mm
height=32mm
ABCΔ ,AC=40mm
AB=32mm
BC^2=40^-32^2(by applying. Pythagoras theorem)
BC=√576
BC=24
Step-by-step explanation:
height=32mm
radii=24mm
CSA=2πrh
=2*3.14*24*32
=4823.04mm
TSA=2πr(h+r)
=2*3.14*24(32+24)
=2*3.14*24*56
=8440.32mm
curved surface area=4823.04mm
total surface area=8440.32mm
