A cone with height h and radius r has volume V = 13πr2h. If h is 12 in. and V is equal to 4πx2 – 24πx + 36π, what is the cone’s
radius r in terms of x?
1 answer:
Answer:
r = |x -3|
Step-by-step explanation:
The cone's volume is ...
The version of that containing x is ...
Comparing one form to the other, we see that ...
The cone's radius in terms of x is r=|x-3|.
