Question

A toy is in the form of a cone of radius 3.5 cm mounted on a
hemisphere of same radius. The total height of toy is 15.5 cm. Find the
total surface area of the toy.

Answer 1

Answer:

Right circular cone

Solve for surface area

A≈213.21cm²

r Radius

3.5

cm

h Height

15.5

cm

Using the formulas

A=πrl+πr2

l=r2+h2

Solving forA

A=πr(r+h2+r2)=π·3.5·(3.5+15.52+3.52)≈213.20692cm²
