The volume of a sphere depends on its radius, so the volume is a function of the radius. If this function is called VC), use the formula below to compute
(3), the volume of a sphere with a radius of 3 units.

Choice C.:

Step-by-step explanation:

The radius is given as 3, and in the formula you have to cube the radius, meaning you have to multiply 3 b y itself 3 times which gives you 27.  If I were to go further in simplifying the formula, I could come down to , but that answer isn't given as a choice, so I go to the second best answer to get which is answer choice C: .

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

for b its (t) and c its (d)
