Step-by-step explanation:
Answer:
In standard form it is x^4 - 12x^3y + 54x^2y^2 - 108x y^3 + 81y^4.
Step-by-step explanation:
(3y)^4 + 4C1(3y)^3(-x) + 4C2(3y)^2(-x)^2 + 4C3(3y)(-x)^3 + (-x)^4
= 81y^4 - 108y^3x + 54y^2x^2 - 12yx^3 + x^4
R = 12/2 = 6 π = 3.14
Circumference of a circle: C = 2πr
2*3.14*6
6.28*6 = 37.68 or 37.69
The last options seems reasonable
Hope that helps!
