Question

I got the answer it is A I just need you to check it pls thank you

Answer 1

We have a circle of radius 5 m inside a square of side 10 m. The shaded area is:

`A_{\text{Shaded}}=A_{\text{Square}}-A_{\text{Circle}}`

Now, we calculate the area of the square and the circle:

`\begin{gathered} A_{\text{Square}}=10^2=100m^2 \\ A_{\text{Circle}}=\pi\cdot5^2=25\pi m^2 \end{gathered}`

Finally, the shaded area is:

`A_{\text{Shaded}}=100-25\pi\approx21.5m^2`
