​

Answer 1

Answer:

Answer:

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=2πr

2+2πrH+πr( h2 +r2 )A=2π×5×5+2π×5×13+π×5( 5 2 +122 ) A=770cm2

Answer 2

Answer:
