Question

Logan and his brother plan to make spherical glass ornaments to decorate their living room. Logan decides to completely fill the glass ornaments with glitter. The glass ornaments have a diameter of 3 inches each. What is the amount of glitter required to completely fill one glass ornament? Use 3.14 for .

Answer 1

For this case the first thing you should do is find the volume of the sphere.
We have then:
V = (4/3) * (pi) * (r ^ 3)
Where,
r: sphere's radius
Substituting values we have:
V = (4/3) * (3.14) * ((3/2) ^ 3)
V = 14.13 in ^ 3
Answer:
The amount of glitter required to completely fill one glass ornament is:
V = 14.13 in ^ 3
