Answer:

200.96

Step-by-step explanation:

Area is

[tex]\pi {r}^{2} [/tex]

Where r is the radius, we can find the radius since the radius is half of the diameter. Since the diameter is 16, the radius is 8. Now let plug it in the equation.

[tex]\pi(8) {}^{2} [/tex]

Which equals

[tex]64\pi[/tex]

Use 3.14 as pi then multiply

[tex]64 \times 3.14[/tex]

Which is 200.96
