To find this you need to know how to find the Circumference and thats 2 x radius x pi (3.14)

then u just plug in your numbers to get your equation
<span>2 x 16 x 3.14</span>

then solve it and it turns out to be <span>100.48

So B is your answer</span>

Order from least to greatest.<br><br>325%, 4, -160%<br>2.5

-160%, 2.5, 325%, 4

In order to make a percentage you take the decimal and move it twice (i.e .97 = 97%) so that would mean that 325% as a number instead of a percentage would be 3.25 and the same for -160% (-1.6).

Math help!!!!!!!!!!!!!!!!!

Luda [366]

Answer:

(0, 4)

Step-by-step explanation:

The y intercept will always be located at x=0. When x=0, y=4, so the y intercept would be written as (0, 4)

Factor this expression completely, then place the factors in the proper location on the grid.

andreev551 [17]

Notice that you have a difference of cubes:

$\dfrac{x^3}8-\dfrac{y^3}{27}=\left(\dfrac x2\right)^3-\left(\dfrac y3\right)^3$

which can be factored using the rule,

$a^3-b^3=(a-b)(a^2+ab+b^2)$

So,

$\dfrac{x^3}8-\dfrac{y^3}{27}=\left(\dfrac x2-\dfrac y3\right)\left(\dfrac{x^2}4+\dfrac{xy}6+\dfrac{y^2}9\right)$

and just to make things look nicer, we can pull out 1/6 from the first factor and 1/36 from the second to get

$\dfrac{x^3}8-\dfrac{y^3}{27}=\dfrac1{216}(3x-2y)(9x^2+6xy+4y^2)$

A sphere has a radius of 5 inches. What is its volume?

jarptica [38.1K]

Given ↓

Radius of sphere = 5 in

<h3>To Find ↓</h3>

The volume of the sphere

<h3>Calculations ↓</h3>

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

↑ formula for volume of a sphere

r = 5 in

Plug in the value of r and solve :

$\blue{\boxed{\mathsf{V=\frac{4}{3}\pi (5)^3}}}$

Simplify as follows :

$\blue{\boxed{\mathsf{V=\frac{4}{3}\pi *125} }}$

$\blue{\boxed{V=\frac{4}{3} *392.7}}$

Final Step :

$\blue{\boxed{\pmb{V=523.6\:in\:^3}}$
