Answer:
11. B.
12. 3
Step-by-step explanation:
![\sqrt[3]{27}=3](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B27%7D%3D3)
since 
V=area of base times height
height=height
area of base=area of circle=pir^2
V=hpir^2
r=6
h=14
V=14pi6^2
V=14pi36
V=504pi
aprox pi=3.141592
V=1583.3 round
V=1583 cm^3

Given that the rate of Uranium decay is 57%, this means that after each day, only 0.43 of the mass from the prior day is left. The equation that would best represent the scenario is,
a(t) = a₁(0.43^t)
where a(t) is the mass after t days and t is the number of days. Substituting,
a(t) = 3,280(0.43^15)
= 0.01 lbs.
