Question

If a 3 metre long roller cover a distance of 4.61 metres in a complete circle, its carved surface area is 13.83 square metres.​

Answer 1

Answer:

True

Step-by-step explanation:

The curved surface area of a cylinder is equal to the area it cover on ground in one complete revolution.

This curved surface will appear as a rectangular piece on ground.

So area will be length×breadth

Here length is 3m and breadth is distance covered by cylinder in one revolution that is 4.61m

So area = 4.61 × 3 => 13.83sq.m

Answer 2

Answer:

CSA = LENGTH * BREADTH ( AREA WILL BE ON GROUND)

= 4.61*3

= 13.83

=TRUE
