Answer:

-11 and -1

Step-by-step explanation:

x² + 12x = -11

x² + 12x + 36 = -11 + 36

(x+6)² = 25

x + 6 = √25

x + 6 = 5

x = 5 - 6

x = -1

x+6 = -5

x = -11

Makovka662 [10]
The answer is 21.2 ft²
To do this we need to calculate the volume of the cylinder shaped drum.The volume (V) of the cylinder with height h and radius r is:V = π r² h
We have:π = 3.14r = 1.5 fth = 3 ft
Therefore:V = π r² hV = 3.14 * (1.5 ft)² * 3 ftV = 21.2 ft²
