Question

If diameter of cylinder is 3.5m and height is 10m.Then its curved surface area is​

Answer 1

Answer:

110m^2

Step-by-step explanation:

curved surface area of cylinder = 2πrh

= 2 × 22/7 × 3.5/2 × 10

= 110m^2

Answer 2

Answer:

Option(b)

Step-by-step explanation:

Diameter = 3.5m

Height = 10m

So curved surface area = 2πrh unit²

                                        = 2πd/2h unit²

                                        = (2 × 22/7 × 3.5/2 × 10) m²

                                        = 110 m²

Option (b) satisfies it
