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

USPshnik [31]

Answer:

$95777.5

Step-by-step explanation:

change 7% to decimal = .07

91,000 * .07 = 5370 (annual interest)

5370 / 12 = 530.83 (monthly interest)

530.83 * 9 = 4777.5 (9 months interest)

91,000 + 4777.5 = 95777.5 (initial + 9 months interest)
