Find the volume of a sphere with a surface area of 3600pi in squared.
Anna71 [15]

Answer:

36000pi

Step-by-step explanation:

V = 4/3*pi*r^3  so we need to know r

we know surface area, which is 4pi*r^2=3600pi.  so we can solve for r

r=30

so v = 4/3*pi*30^3 = 36000pi

Find the distance between each pair of points E(-1, 0),F(12, 0)
Olegator [25]

Answer:

The answer is

<h2>13 \:  \: units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

<h3>d =  \sqrt{ ({x1 - x2})^{2}  +  ({y1 - y2})^{2} }  \\ </h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

E(-1, 0) and F(12, 0)

The distance between them is

<h3>|EF|  =  \sqrt{ ({ - 1 - 12})^{2}  +  ({0 - 0})^{2} }  \\  =  \sqrt{ ({ - 13})^{2} }  \\  =  \sqrt{169}</h3>

We have the final answer as

<h3>|EF| = 13 \:  \: units</h3>

Hope this helps you

What is the slope of the line y= 1
Harrizon [31]

Answer:

The slope of y = 1 is 0

explanation:

Determining slope has been based on a simple formula, y2-y1 over x2-x1.

It is crucial to follow this formula in order to attain the proper slope.

When a simple expression is given, for instance; y = 1 then it could be divided by 0; thus, resulting in the answer simply being zero.

However, x=1  would contain the slope of undefined because any number divided by zero results in an undefined answer.
