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
