The top of a storage container is a hemisphere with a diameter of 28 feet. What is the volume of the storage container? Round yo
creativ13 [48]

Answer:

5749.3 cubic feet

Step-by-step explanation:

The volume of the  storage container would be defined by the volume of the shape; a hemisphere

The volume V of  a hemisphere is given as

V = 2/3 π r^3

where r is the radius of the hemisphere

Given that the diameter is 28 feet, the radius = 14 feet

hence the volume

= 2/3 * π * 14^3

= 5749.333333

To the nearest tenth

= 5749.3 cubic feet

Write an equation in slope intercept form that goes through (-1,6) and (3,-2)
pochemuha
<h2>Answer:</h2>

First, we need to use <u><em>slope formula*</em></u> to find the slope.

m = \frac{-2 - 6}{3 - (-1)} = \frac{-8}{4} = -2

Second, we use the slope we found and <em>ONE</em> of the 2 points listed and plug it into <u><em>slope-intercept form**</em></u> to solve for <u><em>b</em></u>.

Here is what we have so far:

  • m = -2

I'm going to use this point:

  • x = 3
  • y = -2

Here is how to find <em>b</em>:

-2 = -2(3) + b\\\\-2 = -6 + b\\\\4 = b

Finally, we put all of it together and we have our equation.

y = -2x + b

*Slope formula: <em>m = y₂ - y₁/x₂ - x₁</em>

**Slope-intercept form: <em>y = mx + b</em>

<em></em>
