Answer:

$x1=\frac{-5+\sqrt{13}}{2}\\ \\x2=\frac{-5-\sqrt{13}}{2}$

Step-by-step explanation:

x² + 5x + 3 = 0

x = (- 5 +/- √5² - 4x1x3)/2x1

= (-5+/-√13)/2

x₁ = (- 5 + √13)/2

x² = (- 5 - √13)/2

Given, 

Radius of the cylinder = 3cm

Height of the cylinder = 3cm

Therefore, 

Lateral surface area of the cylinder

$= 2\pi rh$

$= 2\pi \times 3 \times 3 {cm}^{2}$

$= 2\pi \times 9 {cm}^{2}$

$= 18\pi {cm}^{2}$

Hence,

The required value in the green box will be 18 (Ans)
