Answer:
d (w) = 0.1w² – w+ 5
Step-by-step explanation:
d(w) = c(w) - a(w)
= -0.3w²+2w+13 -(-0.4w²+3w+8)
= -0.3w²+0.4w²+2w-3w+13-8
= 0.1w²-w+5
volume of cylinder = PI*r^2*h
r=11
h=15
using 3.14 for pi
3.14*11^2*15 = 5699.1 units^3
36.9
it might be wrong but at least i tried
Domain = (-∞ , ∞) or all real numbers
