Answer:
379.94
Step-by-step explanation:
The area of a circle is [tex]\pi r^2 \text{ where r is the radius}[/tex]
But, it has given us the diameter, and diameter is two times the radius, so:
[tex]22\div2=11=\text{radius}[/tex]
Then, we subsitute 11 in the formula and we get:
[tex]\pi 11^2=121\pi \text{ or } 379.94 \text{ millimeters }[/tex]
Hope it helps!!!!!
