Answer:
Step-by-step explanation:
The formula of volume of cone is
V=\frac{1}{3}\pi r^{2} h
where, r is the radius
we have given diameter = 12 =2r
r=6 ft
h is the height h=6 ft
\pi =3.14
Substitute the value in the formula,
V=\frac{1}{3}\pi r^{2} h
V=\frac{1}{3}\times (3.14)\times 6^{2}\times 6
V=\frac{1}{3}\times 3.14\times 36\times 6
V=226.08 ft^3
Therefore, The volume of cone is 226.08 cubic ft.

Answer:
(-5,2)
Step-by-step explanation:
Answer:
The function given is:
P(x) = 15x² + 350x - 2000
or
y = 15x² + 350x - 2000
Interchange x and y:
x = 15y² + 350y - 2000
x = (y√15)² + 2(y√15)(45.19) + (45.19)² - (45.19)² - 2000
x = ( y√15 + 45.19)² - 4042.14
( y√15 + 45.19)² = x + 4042.14
Take square root:
y√15 + 45.19 = (√(x + 4042.14))
y√15 = (√(x + 4042.14)) - 45.19


The minimum value of x, for which function is defined and real, is x= -4042.14
Hence, the range of inverse is x ≥ -4042.14
