Which unit of measure would be appropriate for the volume of a sphere with a radius of 2 meters

stiv31 [10]

<span>A sphere is a perfectly round geometrical object that is three dimensional, with every point on its surface equidistant from its center. Many commonly-used objects such as balls or globes are spheres. If you want to calculate the volume of a sphere, you just have to find its radius and plug it into a simple formula, V = ⁴⁄₃πr³</span>

Which of the following equations is an example of the Associative Property of Addition?

user100 [1]

Answer:

Option B) (5+6)+4=5+(6+4) is correct

An example of the associative property of addition is (5+6)+4=5+(6+4)

Step-by-step explanation:

Given $(5+6)+4=5+(6+4)\hfill (1)$

Verify that the given equation is an example of associative property of addition or not:

We have the associative property of addition

$(a+b)+c=a+(b+c) \hfill (2)$

Comparing the equation (1) and(2) we have the given equation is in associative property

Therefore option B) (5+6)+4=5+(6+4) is correct

An example of the associative property of addition is (5+6)+4=5+(6+4)

Find the number of sides for a regular polygon whose interior angles each measure 10 times each exterior angle

gavmur [86]

Answer:

22 sides

Step-by-step explanation:

The expression to find an interior angle of a polygon is:

$\frac{(n-2)*180}{n}$

The expression to find an exterior angle of a polygon is:

$\frac{360}{n}$

Please note that "n" represents the number of sides the polygon has.

We can use these two expressions to set up an equation.

$\frac{(n-2)*180}{n}=10(\frac{360}{n})$

Multiply both sides by "n":

$(n-2)*180=10n(\frac{360}{n})$

Now, distribute:

$180(n)-180(2)=\frac{3600n}{n}\\180n-360=3600$

Divide both sides by 10:

$\frac{180n}{10}-\frac{360}{10}=\frac{3600}{10}\\$

$18n-36=360$

Add 36 to both sides:

$18n=360+36\\18n=396$

Divide both sides by 18:

$n=22$

The polygon has 22 sides
