Answer:

864ft^3

Step-by-step explanation:

Divide the diameter by 2 to get the radius

12 / 2 = 6

Then solve the volume equation using 3 for pi.

4/3 * 3 * 6^3

4 * 6^3

4 * 216 = 864

Answer:

The value of x is 7.

Step-by-step explanation:

First, you have to make the left side into 1 fraction by making the denormintor the same and make it into simplest form :

$\frac{x}{3} + \frac{x}{6}$

$= \frac{x \times 2}{3 \times 2} + \frac{x}{6}$

$= \frac{2x}{6} + \frac{x}{6}$

$= \frac{2x + x}{6}$

$= \frac{3x}{6}$

$= \frac{x}{2}$

Next you have to multiply both sides by 2 in order to make x the subject :

$\frac{x}{2} = \frac{7}{2}$

$\frac{x}{2} \times 2 = \frac{7}{2} \times 2$

$x = 7$

What is r i 4.5+10r=-6.5 with work pls

Evgen [1.6K]

Answer:

-11/10 or -1.1

Step-by-step explanation:

To start, let's get rid of those pesky decimals by multiplying everything by 2. Then we get 9 + 20r = -13. Now, let's isolate the r by subtracting 9 from both sides to get 20r = -22. Finally, we need to divide everything by 20 to get r = -11/10 or -1.1.

Using the following picture which side is the hypotenuse?

mylen [45]

Hi!

A hypotenuse is the longest leg in a right triangle.

A right triangle is a triangle that has one 90 degree angle.

The hypotenuse is always directly across from the right angle.

In pictures, right angles are represented by a square.

Therefore, the side with the hypotenuse is side 3, because we can see that the angle between side 1 and side 2 is the right angle, and the hypotenuse would be directly across.
