18 inches wide?

Okay, first we need to find the area, which would be $$9^2 $$ multipled by pi, which is about 3.14.

Then, we need to divide it by 8, and 16 to determine the relative slice areas.

For arc lenght, we'll need to find the circumfrance, and divide it for each individual piece.
The formula uses the diameter (18) and pi (3.14).

Then, divide the result by 8, and 18.

The last we need to do is determine the interior angle measurement, which is quite simple with a circle.

Since a circle is 360 degrees, we simply need to divide 360 by 8 and 360 by 16 to get their relative measurements.
