Easy question :- Find the total surface area of a container in cylindrical shape whose diameter is 28 cm and height is 15 cm.

Answer 1

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.
