Answer:
284/3 πx³
Step-by-step explanation:
Volume of a cylinder is expressed as shown:
V = πr²h
r is the radius of the cylinder
r = diameter/2
r = 8x/2
r = 4x
Height of the cylinder = 6x
Volume of the roll with out the hole
V = π(4x)²(6x)
V = 16x²π(6x)
V = 96πx³
The hole in the middle will be a solid sphere with diameter 2x (radius will be x)
Volume of the hole = 4/3πr³
Volume if the hole = 4/3πx³
Volume of the toilet paper roll = volume of the roll without a hole - volume of the hole
= 96πx³ - 4/3πx³
= (96-4/3)πx³
= 284/3 πx³
Answer:
24432.193
Step-by-step explanation:
Volume of sphere = 4/3 pi x cube of radius
Radius =18ft , pi = 3.142
Volume = 4/3 x 3.142 x 18 x 18 x 18
Volume = 1.3333 x 3.142 x 5832
Volume = 24432.19ft3
Volume =24432ft3 to the nearest whole number

To build a scale model we must take into account the original measurements of the original house.
<h3>What is a scale model?</h3>
A scale model is a tool that allows us to build a structure with a smaller or larger size than the original that we take as a reference.
<h3>How to build a scale model?</h3>
To build a scale model we must take into account all the measurements of the original object, in this case a house to be able to reduce it adequately to a smaller scale.
For example, if its sides are 30 meters long by 2 meters high and we want to make a scale of half the size, we must make its sides 15 meters long by 1 meter high.

I think the answer would be "X=1"
(Sorry if I'm wrong)
Im not sure, maybe determined answer B
