Answer:

Step-by-step explanation:
The given quadratic equation is:

Comparing it with the standard form of Quadratic Equation
, we get:
a = 3, b = -9 and c = 1
Discriminant = b² - 4ac
D = (-9)²-4(3)(1)
D = 81 - 12
D = 69

Step-by-step explanation:
x+7+25+2x+4=180
3x+11+25=180
3x=180-36
3x=144
<em>x</em><em>=</em><em>1</em><em>4</em><em>4</em><em>/</em><em>3</em>
<em>x</em><em>=</em><em>4</em><em>8</em>
The correct answer is the fourth one 324\pi cm3
