Answer:
The answer is B.
Step-by-step explanation:
A=3.14 x 12.5>2
A= 3.14 x 156.25 =490-.625
A= 490.625 x 16m
A= 7, 850 m3
Answer:
20ln(3)
Step-by-step explanation:
Put 15 for A and solve for t.
15 = 45e^(-.05t)
15/45 = 1/3 = e^(-.05t) . . . . divide by 45
ln(1/3) = -.05t . . . . . . . . . . . take natural logs
20ln(3) = t . . . . . . . . . . . . . . multiply by 20, simplify
It will take 20·ln(3) years for the area to decrease to 15 km^2.
