Find the total surface area of a cylinder if the radius of its base is 5 cm and height is 40 cm.

Answer :

Radius of base of cylinder, r = 5 cm

Height of cylinder, H = 40 cm

As we know,

Total surface area of cylinder, A = 2πr (r + h)

On substituting the values, we get,

A = 2× (3.14)× 5× (5 + 40)

A = 1413 sq.cm

Total surface area of square is 1413 sq. cm
