Question

Which is the area of the figure? Use 3.14 for PI

Answer 1

First, find the area of the square region (we know it's square since the lengths are given as the same). That would be \(4^2=16 ft^2\). Now we need to find the area of the half circle.

The area of a half circle is \((\pi r^2)/2\) where \(r\) is the radius. The radius is half of the diameter, and we know the diameter to be 4ft. Therefore, the area of the half circle is \[{3.14 \cdot (4/2)^2 \over 2}={3.14 \cdot 2^2 \over 2}=3.14\cdot 2=6.28\]
Now we add the two areas to get. \[16+6.28=24.28 \;\;ft^2\]

Answer 2

Check your math again I got 22.28.

Answer 3

You are correct. I messed up my addition :(
