Please need help I will be MARKING as BRIANILIST. thank you so much. ​​

Answer 1

Answer:C.8.027

Step-by-step

V = s
`^(3)`

The rate of change is found using the first derivative of this function. This is often called the gradient function, because it gives the gradient of a tangent line drawn at the specified point.

`(dV)/(ds)`(s
`^(3)`) =3s
`^(2)`

We now plug in s =6

3s
`^(2)` = 3(6)
`^(2)` = 8.027
`(cm3)/(s)`

Answer 2

12.167(option D)

Solution,

`side \: length(s) = 2.3 \\ volume = {s}^(3) \\ \: \: \: \: \: \: \: \: \: \: = {(2.3)}^(3) \\ \: \: \: \: \: \: \: \: \: \: \: \: \: = 2.3 * 2.3 * 2.3 \\ \: \: \: \: \: \: \: \: = 12.167 \: {cm}^(3) \\`

hope it helps...

Good luck on your assignment....
