Answer:
m=18
Step-by-step explanation:
First add 7 to both sides.
2+7=m/2
Simplify 2+7 to 9
9=m/2
Multiply both sides by 2
9*2=m
Simplify 9*2 = 18
18=m
Answer: 
Step-by-step explanation:
Using the area formula of a cone, find the height first.

Solve for h,
Begin by dividing by 

Subtract r.

Square both sides.


Subtract 

Extract the square root.


Plug in your values.
![\sqrt{[\frac{670cm^2}{(3.14)(8cm)}-(8cm)]^2-(8cm)^2 } =h](https://tex.z-dn.net/?f=%5Csqrt%7B%5B%5Cfrac%7B670cm%5E2%7D%7B%283.14%29%288cm%29%7D-%288cm%29%5D%5E2-%288cm%29%5E2%20%7D%20%3Dh)
Solve;
![\sqrt{[\frac{670cm^2}{25.12cm}-(8cm)]^2-(8cm)^2 } =h](https://tex.z-dn.net/?f=%5Csqrt%7B%5B%5Cfrac%7B670cm%5E2%7D%7B25.12cm%7D-%288cm%29%5D%5E2-%288cm%29%5E2%20%7D%20%3Dh)
