Answer:

200.96

Explanation:

We know that the area of a circle is
\pi r^2

But we are given the diameter. Diameter is two times radius, so:
\frac{\text{diameter}}{2}=\text{radius} = (16)/(2)=8\\

We now know that 8 is our radius. Then, we will use the formula to solve.


\pi r^2=\pi8^2=64\pi \text{ or } 200.96|

HOPE THIS HELPS!!!!
