What is the approximate area of the following circle?

Answer:
[tex]38.47 {m}^{2} [/tex]
Step-by-step explanation:
The formula to find the area of a circle is
[tex] a= \pi {r}^{2} [/tex]
We know that
[tex]\pi = 3.14 \: \: \: \: \: \: r = 3.5[/tex]
Therefore the area is
[tex] a= \pi {r}^{2} \\ \\ a = (3.14) {(3.5)}^{2} \\ \\ a = 3.14 \times 12.25 \\ \\ a = 38.47 {m}^{2}[/tex]
