Answer 1

2 should be the answer

Answer 2

Given,

The final shape is = Semicircle

To find,

Number of quater circles needed to build the final shape or a semicircle.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Now,

Semicircle = ½ of a complete circle

Quarter circle = ¼ of a complete circle

Let, complete circle = x

So,

Semicircle = x/2

Quarter circle = x/4

Number of quarter circles needed = x/2 ÷ x/4 = x/2 × 4/x = 2

Hence, 2 quarter circles will be needed to form a semicircle. (Option 3)
