Question

(iv) Find the total surface area of the cylinder, if the radius of its base is 5 cm and
height is 40 cm.
( TI = 3.14)​

Answer 1

Answer:

Given:

For the cylinder,

radius (r) = 5 cm,

height (h) = 40 cm

To find:

Total surface area of the cylinder.

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

= 2 × 3.14 × 5 (5 + 40)

= 2 × 3.14 × 5 × 45

= 1413 cm²

The total surface area of the cylinder is 1413cm²
