Answer:
21+3t
If really want equation answer it would be -7 but it simplifying. :)
Step-by-step explanation:
6(4+t)-3(t+1)
Simplify parenthesis first.
24+6t-3t-3
Simplify like terms
24-3+6t-3t
21+3t

Answer:
![r=22.07\ in](https://tex.z-dn.net/?f=r%3D22.07%5C%20in)
Step-by-step explanation:
<em><u>The correct function is</u></em>
![m(r)=7.188\pi r^{2}](https://tex.z-dn.net/?f=m%28r%29%3D7.188%5Cpi%20r%5E%7B2%7D)
we have
System of equations
-----> equation A
-----> equation B
Solve by substitution method
substitute equation B in equation A
![11,000=7.188\pi r^{2}](https://tex.z-dn.net/?f=11%2C000%3D7.188%5Cpi%20r%5E%7B2%7D)
Solve for r
Divide by 7.188π both sides
![r^{2}=\frac{11,000}{7.188\pi}](https://tex.z-dn.net/?f=r%5E%7B2%7D%3D%5Cfrac%7B11%2C000%7D%7B7.188%5Cpi%7D)
square root both sides
![r=22.07\ in](https://tex.z-dn.net/?f=r%3D22.07%5C%20in)
