Question

A rocket is in the form of a cucular cylinder
closed at the lower end and a cone of the
same madius is allached to the top. The readiu
eerte of canvas needed of the cylinder in
Hs height is 2.m and the slont height
of the cone is om. Calculate the total
suface area of the racket.
of the
2.sm​

Hope the answer is usefull...

Answer 2

Answer:

Total surface area = Area of base of cylinder+ Area of curved surface of cylinder+Area of curved surface of cone

A=π×r

2

+2πrh+πrl

h=height of cylindrical part

l=slant height of conical part

r=radius of cylinder=radius of cone

A=π×2.5

2

+2π×2.5×21+π×2.5×8

A=412.334m
