Question

In figure 7.11. a toy made from a
hemisphere. a cylinder and a cone
is shown. Find the total area of the
$\pi = 3.14$
​

Answer 1

Answer:

total area of toy = csa of cylinder+ csa of hemisphere + curved surface area of cone

=> 2πr^2+ πrl + 2π rh

=> 2×3.14×3×3+3.14×3×4+2×3.14×3×40

=>18.84+37.68+553.6

=>610.12 cm^2 ans
