Question

Find (i) the curved surface area and (ii) the total surface area of a hemisphere of radius 3.5 cm.

Answer 1

(i) The curved surface area of a hemisphere of radius 3.5 cm would be 2$\pi$$r^2$ = 77${cm}^2$

(ii) the total surface area of the hemisphere would be 3$\pi$$r^2$ = 115.5 ${cm}^2$
