Answer:

6,000 children

Step-by-step explanation:

1/3 of 9,000 is 3,000

Meaning that out of 9,000 children, 3,000 WILL get affected. Since we are trying to figure out how many children will NOT get affected, just subtract the number of infected by the total amount which would be 6,000

Cones A and B both have volume cubic 48 π units, but have different dimensions. Cone A has radius 6 units and height 4 units. Fi
Alex_Xolod [135]

Answer:

A possible solution is that radius of cone B is 2 units and height is 36 units

Step-by-step explanation:

The volume of a cone is given by

V=\frac{1}{3}\pi r^2 h

where

r is the radius

h is the height

Here we are told that both cones A and B have the same volume, which is:

V_A=\frac{1}{3}\pi r_A^2 h_A = 48 \pi

And

V_B=\frac{1}{3}\pi r_B^2 h_B = 48 \pi (2)

We also know that cone A has radius 6 units:

r_A=6

and height 4 units:

h_A=4

For cone B, from eq.(2), we get

\frac{1}{3}r_B^2 h_B = 48\\r_B^2 h_B = 48\cdot 3 =144

One possible solution for this equation is

r_B = 2\\h_B = 36

In fact in this case, we get:

r_B^2 h_B = (2)^2\cdot 36 = 4\cdot 36 = 144

Therefore a possible solution is that radius of cone B is 2 units and height is 36 units, and we know that in this case Cone B has the same volume as cone A because it is told by the problem.
