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
