DIA [1.3K]

The maximum radius of each ball is 3.33 cm.

<h3>What is a Cylinder?</h3>

A cylinder is a three-dimensional figure which is made of two parallel circular bases separated at a certain distance by a curved surface of the same radius as that of the bases.

A 20 cm nail perfectly fits the cylinder.

So the height of the cylinder = 20cm.

A sphere is a three-dimensional geometrical figure analogous to a circle. All the points of the sphere are at the same distance from the center.

If 3 spheres have to be fitted inside the cylinder,

The sum of the diameter of the spheres will be equal to the height of the cylinder.

The spherical balls are identical and so will have the same diameter

Let the maximum diameter of the sphere that can fit in the cylinder is d cm

Then,

d + d + d = 20

3d = 20

d = 20/3 = 6.67 cm

r = 3.33 cm

The maximum radius that the spheres can have to fit in the cylinder is 3.33 cm.

At Tanika's school, 3 people are chosen in the first round. Each of those people chooses 3 people in the second round, and so on
notka56 [123]
96 people. With every round, the number of people doubles. 3 turns into 6, which turns into 12, which turns into 24, which turns into 48, which turns into 96. The process is repeated only 5 times, but keep in mind when 3 people are chosen, it ends the first round. Hope this helps!!!
