Question

a fez, the headberg cap used by the trucks is shaped like the frustum of a cone. If a radius on the open side is 10cm, radius at the upper base is 4cm and its slant height is 15cm, find the area of material used for making it.​

Answer 1

Answer:

r1=10cm,

r2=4cm and

slant h=15cm.

Area of the material used = Curved Surface area + Area of the closed base

=π(r1 + r2)l + πr square

=22/7× (10+4) × 15 + 22/7 × (10)square

=(660+352/7)

=660 + 50.28

=710.28 cm2
