Question

Find curved surface area of a cylinder whose radius = 3.5cm and
height = 25cm?

Answer 1

Answer:

550

Step-by-step explanation:

2πrh is the C.S.A of cylinder so,

2*22/7*3.5*25=550 is the C.S.A of cylinder

Answer 2

The correct answer is 550 $cm^{2}$.

Given: Radius(r) = 3.5 cm.

Height(h) = 25 cm.

To Find: Curved surface area of cylinder.

Solution:

Curved surface area of cylinder = $2\pi rh$

$2\pi rh$

= $2*\frac{22}{7}*3.5*25$

= 550

Hence, the curved surface area of cylinder is 550 $cm^{2}$.
