Because the balls or spheres are tightly packed in a cube, their radius is approximately equal to 2 ft. The volume of a sphere is calculated through the equation,
V = 4/3πr³
Substituting the known radius,
V = 4/3π(2 ft)³
V = 33.51 ft³
The 9 spheres will have a total volume of 301/59 ft³ which is also equal to 521152.52 in³.

Answer:

r= 7.14 (rounded to 2 decimal places)

Step-by-step explanation:

We have to solve this equation for the value of r. We will use distributive property and basic algebra to solve this.

Distributive property is a(b+c) = ab + ac

Now, the steps of solving are shown below:

$-3r-8(8r+8)=-9(-4+9r)\\-3r -64r-64=36-81r\\-67r-64=36-81r\\-67r+81r=36+64\\14r=100\\r=\frac{100}{14}\\r=7.14$

Hence, value of r is 7.14 (rounded to 2 decimal places)
