Question

A right circular cylinder is 6.5 high and it's circumference office base is 46 m. find its curved surface area​

Answer 1

Answer:

Curved surface area of the cylinder = 298.95 square m

Step-by-step explanation:

Height of the cylinder = 6.5 m

The circumference of the base = π × 2 × radius = 46m

Therefore radius of the cylinder = 46 / ( π × 2)

            radius r = 7.32 m

Curved surface area of the cylinder = π × 2 × radius × height

                                                           = π × 2 × 7.32 ×6.5

                                                           = 298.95 square m
