Answer:

379.94

Explanation:

The area of a circle is
\pi r^2 \text{ where r is the radius}

But, it has given us the diameter, and diameter is two times the radius, so:


22/2=11=\text{radius}

Then, we subsitute 11 in the formula and we get:


\pi 11^2=121\pi \text{ or } 379.94 \text{ millimeters }

Hope it helps!!!!!
