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
A square with sides measuring 4 m has a quarter circle attached with with the same measurements.

Answer:

28.6 m²

Explanation:

The measurements of the square are 4 by 4; this gives us an area of

4(4) = 16 m²

The quarter circle has a radius of 4 m. The area of a circle is given by

A = πr².

Since we have a quarter circle, we multiply this by 1/4:

A = 1/4πr²

Using 3.14 for π and 4 for r,

A = 1/4(3.14)(4²) = 1/4(3.14)(16) = 3.14(4) = 12.56 m²

Together this gives us a total area of 16+12.56 = 28.56 m².

This rounds to 28.6 m².
