Answer:

x- 14= 20 answer x=34

c + 5=13 answer c=8

8x=72 answer x=9

m/4 = 8 answer m=32

Step-by-step explanation:

brainlest? please?

Let's solve your equation step-by-step.

x−14=20

Step 1: Add 14 to both sides.

x−14+14=20+14

x=34

______

Let's solve your equation step-by-step.

c+5=13

Step 1: Subtract 5 from both sides.

c+5−5=13−5

c = 8

_____

8x/8= 72/8

x= 9

____

m/4 • 4= 8 • 4

m = 32

What is the best approximation of the surface area of this right cone?

inn [45]

$\bf \textit{total surface area of a cone}\\\\
s=\pi r\sqrt{r^2+h^2}+\pi r^2\quad 
\begin{cases}
r=radius\\
h=height\\
-----\\
r=12\\
h=9
\end{cases}
\\\\\\
s=\pi (12)\sqrt{12^2+9^2}+\pi (12^2)\implies s=12\pi \sqrt{225}+144\pi 
\\\\\\
s=12\pi (15)+144\pi \implies s=180\pi +144\pi \implies s=324\pi$
