a toy is in the shape of a right circular cylinder surmounted by a cone. The radius and
height of the cylindrical part are 3 cm and 13 cm respectively. If the radii of the conical
part is same as that of cylindrical part and total height of the toy is 17 cm then find its
surface area.

Height of the cylindrical part =13cm
Radius of cone , cylinder and hemi sphere=5cm
r=5cm for hemisphere cylinder and cone.
Height of cone h=30−5−13=12
The area of canvas required=Surface area of hemishphere,cylinder and cone parts of tent
A=2πr2+2πrH+πr(h2+r2 )
A=2π×5×5+2π×5×13+π×5( 52+122)
A=770cm2
