Answer 2

Answer:

Step-by-step explanation:

This is a question on area of a cylinder .

It can be understood that there are two cylinders. One big and the other small.

Since the height / length of the cylinder is the same i.e 15 cms, we take into consideration only the radius aspect to find out how many pieces can be carved out.

1)  Cylinder (Small) :

   Radius = d(diameter) / 2

    Radius = .5/2

    Radius = .25

2) Cylinder (Big ) :

 Radius = 1.5 / 2

  Radius = .75

We can conclude , that the number of pieces that can be carved is          .75 / .25 = 3 pieces

Ans. 3 pieces
