Question
Find the total surface area of a container in cylindrical shape whose diameter is 28 cm and height is 15 cm.
Answer
Solution, Given, diameter = 28 cm, so radius = 28/2 = 14 cm
and height = 15 cm
By the formula of total surface are, we know;
TSA = 2πr (h + r) = 2x 22/7 x 14 x (15 + 14)
TSA = 2 x 22 x 2 x 29
TSA = 2552 sq.cm
Hence, the total surface area of container is 2552 sq.cm.

CSA = 2*π*r*h
TSA = 2*π*r*(r+h)
