Answer:
5 * 10 * 10 * 9 = 4500
Step-by-step explanation:
Regular polygon can be incribed in a circle of radius equal to its side.
so if you join all the vertices to the centre, you will get 6 equilateral triangles. each interior angle will have 2 angles of 60 each. thus interior angle = 120
exterior angle=180-120=60
Answer:
(8n^4-6n+8n^2)+(6n^4-4)
8n^4 + 8n^2 - 6n + 6n^4 - 4
<u>14n^4 + 8n^2 - 6n - 4</u>
Step-by-step explanation:
