If you need to show work I can put it in the comments :)
<span>Generate a function for the height of the cyliner as a function of radius. Use this function to generate a function of r for the material used. Take the derivative of that function, set it to zero, and solve for r.
</span><span>V=πr2h</span>h=d h=d=2r h=2r <span>V=πr22r
</span><span>V(r,h)=180.5=πr2h⟹h=<span>180.5/<span>πr2</span></span></span><span>⟹A(r)=r(r+h)=r2+<span>180.5/<span>πr

Answer:
The value of a = 8.
The value of b = 2.
Step-by-step explanation:
Given: where, x = -2
Since, the power is even (10), the resultant will be a positive number.
So, we have:
Note that:
Also,
Therefore, we get:
Hence, a = 8; b = 2
Hence, the answer.
