If the whole diameter of sphere is 6 inch(means radius is 3 inch) & thickness of material is 1 inch, so the radius of the hollow part should be 2 inch (3-1=2)
The total volume of the ball will be;
= Total volume - Volume of hollow part
= 4/3πr³ - 4/3πr³
= 4/3 × 3.14 × (3)³ - 4/3×3.14×(2)³
= 4 × 3.14 × 9 - 4/3 × 3.14 × 8
= 113.04 - 33.52
= 79.52
If the density of the material is 3.25 g/in3, then the density of 79.52 inch³ should be;
= 79.52 × 3.25
= 258.44 g
Now, if there are 8 spheres in one box, the weight if box will be;
= 258.44 × 8
= 2,067.52 g

Ahh! Finally done with this, if you have any doubt just do ask me :)
-4<x<6
should be the correct answer because x is larger than -4 but 6 is larger than x.
you could also write it
-4<x AND x<6
The answer is C because the formula is 2 x pai x radius
Answer:
0
Step-by-step explanation:
-20.5 is the same as -20.5
, since anything to the zero power is equal to 1.
412 divide by 84 how many times can 84 go into 412
84 can go into 412, 4 times and four time 84 equals
331, then continue dividing 84 into the number you obtain by sutracting the number before and the multiple of 84 and x
your answer will be 4.904
