As we cab see it is given clearly in the diagram that the diameter of the sphere in question is 12 units. Therefore, the radius of the sphere will be half of the diameter and thus, it will be:

radius, r=\frac{diameter}{2}=\frac{12}{2}=6 units.

Now that we know the value of the radius, r, we can find the surface area of the sphere by applying the following formula:

Surface Area=4\pi r^2

Therefore, Surface Area=4\pi(6)^2=4\times 36\times \pi=144\pi unit squared

Thus, out of the given options, Option C is the correct answer.

It is C because 4 pi r^2 is the surface area equation. 4 times 6 squared= 144. 144pi = surface area.

Solve the inequality |* +31 &lt; |2x + 1.<br> |x+3|&lt;|2x+1|
Kisachek [45]

Answer:

Step-by-step explanation:

Here are the steps to follow when solving absolute value inequalities:

Isolate the absolute value expression on the left side of the inequality.

If the number on the other side of the inequality sign is negative, your equation either has no solution or all real numbers as solutions.

If your problem has a greater than sign (your problem now says that an absolute value is greater than a number), then set up an "or" compound inequality that looks like this:

(quantity inside absolute value) < -(number on other side)

OR

(quantity inside absolute value) > (number on other side)

The same setup is used for a ³ sign.

If your absolute value is less than a number, then set up a three-part compound inequality that looks like this:

-(number on other side) < (quantity inside absolute value) < (number on other side)

The same setup is used for a £ sign

Dimas [21]

Answer:

<h2>x= -3</h2>

Step-by-step explanation:

Answer:

{2}^{7}

Step-by-step explanation:

{2}^{7}  = 128

{7}^{2}  = 49

So,

128 > 49 \\  {2}^{7}  \:  \:  \:  \:    >  {7}^{2}

Therefore 2^7 is greater
