Question

anyone can solve then please

Answer 1

r=5cm
total height=41cm
height of cylinder,h=41-(12×2)=41-24=17cm
height of cone,H=12cm
slant height,l=√H²+r²
=√12²+5²
=√144+25
=√169
l=13cm

total surface area =surface area of one cone×2+surface area of cylinder
=2×πrl+2πrh
=2πr(l+h)
=2×3.14×5(13+17)
=31.4×30
=314×3
=942cm²

I hope the answer is correct and would be useful for u
