Question

The radius of a roller is 7m and its length is 10m.100 rotations
of the roller are required to level the ground. The area of the ground level?​

Answer 1

Answer:

44000m²

Step-by-step explanation:

First we require to find the circumference of the base circle of the cylinder which would be

2πr hence 2x22/7x7 = 44 m

Now we need to multiply this with length of the Cylinder

44m x 100m = 4400m²

Now we have found the area of the covered by cylinder in one rotation, hence we can find area covered in 100 rotations

4400m²x100 = 44000m²

Hope this helps!
