What is the radius of the cone?
an oblique cone has a height equal to the diameter of the
base. the volume of the cone is equal to 18x cubic units.
2 units
3 units
6 units
9 units

Radius = 3 units

Step-by-step explanation:

The volume of the cone is equal to [tex]18\pi[\tex] cubic units.

Also given that diameter is equal to height. Hence h = 2r

Volume of cone is given as

[tex]V=\frac{1}{3}\pi r^2h[\tex]

[tex]V=\frac{1}{3}\pi r^2(2h)[\tex]

Given

[tex]V = 18\pi[\tex]

[tex]18\pi=\frac{2}{3}\pi r^3[\tex]

[tex]18=\frac{2}{3}r^3[\tex]

[tex]r^3=\frac{3}{2} \times 18[\tex]

[tex]r^3=27[\tex]

[tex]r=3[\tex]

And hence radius is 3 units.

step-by-step explanation:

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
