Write your answer in the simplest radical form

Arada [10]

Answer:

6±2√3

Step-by-step explanation:

We can use the quadratic equation to solve x²-12x+24=0. The special quadratic formula (used when the x term has an even coeffcient, in this case it does) is (-b'±√(b'²-ac))/a where in this case a=1, b= -6, and c=24.

Plugging these in, we get {-(-6)^2±√[(-6)²-1*24]}/1. When we simplify, we get 6±√(36-24) → 6±√12 → 6±2√3. Hope this helps!

Find the radius of a sphere with a volume of 2304 pi cubic centimeters.

Shalnov [3]

Answer:

The radius of a sphere would be 12 cm.

Step-by-step explanation:

The formula for the volume of the sphere =

$V=\frac{4}{3}\pi r^3$

By putting the value of volume we can find the radius of the sphere.

Volume of the sphere = 2304 π cm³

$2304\pi =\frac{4}{3}\pi r^3$

$2304=\frac{4}{3} r^3$

$2304\times \frac{3}{4}=\frac{3}{4}\times \frac{4}{3}r^3$

$2304\times \frac{3}{4}=r^3$

576 × 3 = r³

$r=\sqrt[3]{1728}$

r = 12

The radius of a sphere would be 12 cm.

Please see picture to solve the volume of this figure.

Gemiola [76]

For this case we have that by definition, the volume of a rectangular prism is given by:

$V = a * b * c$

Where:

a: Long

b: Width

c: High

Prism 1:

$V_ {1} = 7 * 6 * 1 = 42 \ cm ^ 3$

Prism 2:

$V_ {2} = 7 * 3 * 4 = 84 \ cm ^ 2$

Thus, the total volume is:

$V = 42 + 84 = 126 \ cm ^ 3$

Answer:

$126 \ cm ^ 3$
