Answer:

n =-19

Step-by-step explanation:

3* (n+7) = -36

Distribute

3n+21 = -36

Subtract 21 from each side

3n+21-21 = -36-21

3n = -57

Divide by 3

3n/3 = -57/3

n =-19

What is the volume of a cone with the diameter 12 CM in height 4 cm

Romashka [77]

The formula for the volume of a cone is

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

to find the radius divide the diameter by 2

$\begin{gathered} r=\frac{D}{2} \\ r=\frac{12}{2} \\ r=6 \end{gathered}$

replace all data in the formula

$\begin{gathered} V=\pi\cdot(6^2)\cdot\frac{4}{3} \\ V=\pi\cdot36\cdot\frac{4}{3} \\ V=(48\pi)cm^3^{} \end{gathered}$
