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!
