If s is a factor of 16 then the gcf of s and 16 is 16 true or false
Travka [436]

Answer:

Step-by-step explanation:

It's not exactly true.

Suppose s = 4

It is a factor of 16. The greatest common factor between 4 and 16 is not 16. It would only be 4.

So the answer to the question is false.

The volume of a cone is V=1/3*pi*r^2*h

Since the value of r is 6 and the value of h is 8, we get:

V=1/3*pi*6^2*8

V=1/3*pi*36*8

V=12*pi*8

V=96pi

V=301.5928947

So the exact volume of the cone is 301.5928947 m^3

The approximate value of the volume rounded to the nearest tenth is 301.6 m^3
