Spheres and radius related question

Question

Ice cream is sold to stores in cylindrical containers with a radius of 10 cm and a height of 21cm. Each scoop of ice cream is a sphere with a radius of 2.1 cm

About how many scoops of ice cream can each container hold?

Answer 1

Volume of a cylinder = the area of the round base x height of the cylinder

V = Bh = π * r^2 * h

Plug in the given radius and height for the cylinder and use a calculate to solve for volume of cylinder

Volume of a sphere = 4/3 * π * r^3

Plus in the given radius for one small scoop of ice cream

How many times can you scoop to get close to the calculated volume of cylinder?

So, let's assume you got 11.11 cm^3 for the cylinder and 0.55 cm^3, then you get 20 scoops out of the cylinder.
