We can do it with the equation written; we'll try that next. I find it easier to remember the exterior angles, which are the supplements of the interior angles, add to 360 degrees.
The exterior angle is 180 - 144 = 36 degrees. n = 360/36 = 10
Answer: 10 sides
Let's try it your way now.
Answer:

Step-by-step explanation:
area of a cricle is
πr^2
take π to be 22÷7
A= πr^2
A=22÷7*15*15
A=22÷7*225
7 divides 225
= 34.142
22*34.142
A= 751.124
