Answer:

Total Surface Area of Solid = C.s.a of hemisphere+C.s.a of cone+C.s.a of Cylinder

slant height of cone=√h²+r²

=√6²+8²

=√100

=10cm

height of cone = 10 cm

radius of hemisphere =radius of cone=radius of cylinder=8cm

T.S.A of solid=2πrh+2πr²+πrl

=πr[2h+2r+l]

=3.14*8[2*10+2*8+10]

=25.12[36+10]

=25.12*46

=1155.52 cm²

Answer:

Height of the cylindrical part and cone are 10cm and 6cmrespectively

Radius of cone , cylinder and hemi sphere=3.5cm

r=3.5cm for both Cylinder and cone

The area of canvas required=Surface area of hemishphere,cylinder and cone parts of tent

A=2πr
