Question

A wooden article was made by scooping out a hemisphere from each
end of a solid cylinder, as shown in given figure If the height of
the cylinder is 10 cm, and its base is of radius 3 5 cm, find the
total surface area of the article

Gopal Mohanty · Accepted Answer

Given that,
Radius (r) of cylindrical part = Radius (r) of
hemispherical part = 3 5 cm
Height of cylindrical part (h) = 10 cm
Surface area of article = CSA of cylindrical part + 2 × CSA
of hemispherical part
