Answer:
452.16 cm³
Step-by-step explanation:
I assume the shape of the volcano is a cone.
V = (1/3)πr²h
r = d/2 = 12 in./2 = 6 in.
V = (1/3)(3.14)(6 in.)²(12 in.)
V = 452.16 in.²
Answer:
Step-by-step explanation:
Radius r = 6 inches
Height h = 12 inches
volume of cone = πr²h/3 ≈ 3.14∙6²∙12 = 1,356.48 in³

Step-by-step explanation:
I'd say an outlier. P is separated noticably from the other points and would not considerably affect the slope of the line
You are comparing velocities. Without a given acceleration, the time can not be found.
X^2 - 5x + 4
-2x^2 + 10x -8
Answer:
3>=3
Step-by-step explanation:
2(4+2x)>=5x+5
distribute the 2: 8+4x>=5x+5
8>=x+5
3>=x
