Quadratic Formula

x = -b +- sqrt{b^2 - 4ac}/(2a)

For question H, subtract 4 from 10 and equate to 0. We now let a = 5, b = -7 and c = 6.

Plug into the formula and do the math..

For question I, subtract 7 from 13 and equate to 0. We know let a = 6, b = 2 and c = 6.

Plug into the formula and do the math.

The base diameter and the height of a cone are both equal to x units.
HACTEHA [7]

By definition, the volume of a cone is given by:

V = (\frac{1}{3}) * (\pi) * (r ^ 2) * (h)

Where,

r: cone circular base radius

h: height of the cone

Substituting values we have:

V = (\frac{1}{3}) * (\pi) * ((\frac{x}{2}) ^ 2) * (x)

Rewriting the equation we have:

V = (\frac{1}{3}) * (\pi) * (\frac{x^2}{4}) * (x)

V = (\frac{1}{12}) * (\pi) * (x ^ 3)

Answer:

An expression that represents the volume of the cone, in cubic units is:

V = (\frac{1}{12}) * (\pi) * (x ^ 3)

Note: rewrite the options again.
