Question

A right a right circular cylinder is 3 metre high and the circumference of its base is 22 metre find its curved surface area

Answer 1

Answer:

As we know,

The curved surface area of the right circular cylinder

=Area of the rectangular sheet

=2×pi ×radius×height

= perimeter of base×height

Now,applying perimeter ×height, we get

=22m ×3m=66 square metres which is the curved surface area of the right circular cylinder.

If you have any doubt, comment on the above answer, if you please the answere, mark me as brainliest.

Answer 2

Answer:

66m

Step-by-step explanation:

csa of cylinder = 2*pi*r*h

2*pi*r = circumference

therefore, csa = 22*3

                       = 66
