Question

a toy in the form of cone mounted on a hemisphere. The diameter of the base and the height of cone are 6cm 4cm. Determine the surface area of the toy. [use π=3.14]​

Answer 1

Answer:

diameter=6

r=d÷2

=6÷2

=3

height=4cm

slant height(l)=√r×r+√h×h

=√3×3+√4×4

=√9+√16

=√25

=5

CSA of a cone =πrl

=3.14×3×5

=62.8
