Question

What is the answer for this question

Answer 1

The yellow region is 13.73 cm squared

Explanation:

---

Area of square:

`8 * 8 = 64 cm^2`

Area of the 4 quarter-circles:

`4(\pi r^2)/4`

The fours cancel each other, we are left with:

`\pi r^2`

r = 4, so substitute that, we get:

`\pi 4^2 = 16 \pi cm^2`

Which can be approximated to 50.27 cm squared

Subtract the area of the circle from the square:

`64 - 50.27 = 13.73 cm^2`

So the area of the yellow region is 13.73 cm squared
