S=(4πr^3)/3, H=(4πr^3)/6

S/H=2rs^3/rh^3

S/H=(2*3^3)/6^3

S/H=54/216

S/H=1/4

So the volume of the hemisphere is 4 time the volume of the sphere.

Volume of a sphere:
V=4/3 π r³

V=4/3 π 3³ = <span>113.097335529
</span>
Volume of a Hemisphere:
V=½(4/3 π r³)

V=½(4/3 π 6³) = <span>452.389342117
</span>
113.097335529 to 452.389342117

Pretty much 1/4 right on the nuts (0.24999999999944737866981989309472)

The three-dimensional figure below is a solid rectangular prism with a hole in the shape of another rectangular prism going thro
vekshin1

So you need to find the volume for the rectangular prism (1) and the rectangular prism in the center of it (2)

The formula for a rectangular prism is:    

V = lwh         [Volume = length x width x height]      

1.

l = 15

w = 6

h = 6

V = lwh           Plug in the numbers

V = (15)(6)(6) = 540

2.

l = 15

w = 4

h = 4

V = lwh

V = (15)(4)(4) = 240

Next you subtract the volumes by each other because the rectangular prism in the center(2) is the hole/empty part of the rectangular prism(1)

V = V(1) - V(2)

V = 540 - 240

V = 300

Find the slope of the line y= -3x+7
Softa [21]

Answer:

<h3>If you had a line of x = 7, (or any time you have an equation where x equals a number) then you would have a vertical line. In every vertical line, the slope is undefined. In equations of lines that are in the format of y = mx + b, the slope is represented by the "m".</h3>
