Answer:
50.24
Step-by-step explanation:
A = Area
Radius = 4 (The radius is half of the diameter

Pie = 3.14
A = (pie)r^2
A = (3.14)4^2
A = (3.14)16
A = 50.24
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
