Question

A quarter circle is attached to the side of a square as shown.

What is the best approximation for the area of this figure?

Use 3.14 to approximate pi.


28.6 m²

41.1 m²

66.24 m²

116.5 m²

Answer 1

-TalibShaheed
The area of the square is YxY
= 4×4 = 16 m²
The area of a quarter circle is (πr²)/4
= 3.14 × 16/4
= 3.14 ×4
= 12.56 m²
That means, the total area is:
= 28.56 m²
Or it will be about:
≈ 28.6 m²
Hope it helped!

Answer 2

The area of the square is s×s
= 4×4 = 16 m²
The area of a quarter circle is (πr²)/4
= 3.14 × 16/4
= 3.14 ×4
= 12.56 m²
Therefore, the total area is;
= 16 +12.56
= 28.56 m²
≈ 28.6 m²
