The surface area of cylinder =2πrh
The surface area of cone =πrl
l2=h2+r2
Where,
1= slant height of the cone
h= height
r= radius
Calculation:
‌l2=h2+r2
‌⇒l2=122+52
‌⇒l2=144+25
‌⇒l=13cm
The surface area of the remaining figure = surface area of cylinder +2× Curved surface area of the cone
‌⇒2πrh+2πrl
‌⇒2πr(h+1)
‌⇒2π×5(30+13)
‌⇒430π
