49π cm²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here diameter = 14, so r = 14 ÷ 2 = 7, then
A = π × 7² = 49π cm²

Since it's a quadrilateral, the measures of the angles have to add up to 360. First, subtract 216 (108×2) from 360 to get 144. Now divide 144 by 4 since you have 4x's that must add to 144. When you do the math, you'll find x=36. So the answer is A.
