A dodecagon is a polygon that has twelve sides. A regular dodecagon has twelve internal angles of 150 degrees each.

Use the formula A=pi x r2. Divide the diameter by 2 then that gives the radius. Substitute the value for radius in the formula. Then that's the answer. (Use 3.14 for pi)

If the 12-sided polygon is 'regular', then each of its exterior angles is 30 degrees. Whether the polygon is regular or not, all 12 of its exterior angles still add up to 360 degrees, but they may not all be equal.

The formula for calculating the area of a circle is 'pi r squared,' where 'r' represents the radius of the circle. A radius of a circle is, of course, half its diameter. Therefore, divide the diameter (24) by 2, then square it, then multiply that figure by pi. Twenty-four divided by two is twelve. Twelve squared is 144. So, multiply 144 by pi and 'Bob's your uncle.'
