Answer:
C
Step-by-step explanation:
A cylinder is formed when rotating the 3-D figure around y-axis
The complete question in the attached figure
we have that
for c=5 and n=20------------> n*c=20*5=100
for c=2.5 and n=40------------> n*c=40*2.5=100
for c=2 and n=50------------> n*c=50*2=100
for c=1.25 and n=80------------> n*c=80*1.25=100
therefore
<span>the function that models the data is n*c=100
</span>
the answer is nc=100
Answer:
A = pi * r^2 = pi * 5^2 = 25*pi = 78.54 in²
