Answer:
<em>The total surface area of the seven little spheres is 1.91 times the total surface area of the bigger sphere.</em>
Explanation:
<u>Volume of a Sphere</u>
The volume of a sphere of radius r is given by:
The volume of each little sphere is:
When the seven little spheres coalesce, they form a single bigger sphere of volume:
Knowing the volume, we can find the radius rb by solving the formula for r:
Multiplying by 3:
Dividing by 4π:
Taking the cubic root:
Substituting:
The surface area of the seven little spheres is:
The surface area of the bigger sphere is:
The ratio between them is:
The total surface area of the seven little spheres is 1.91 times the total surface area of the bigger sphere.
