Ratio=4.0 *10⁷ Krill / day
amount of krill=ratio * days
amount of krill=(4.0*10⁷ Krill /day)(3.65*10² days)=1.46*10¹⁰ krill
Answer: 1.46*10¹⁰ krill
The amount of water that will fill the tank is 11100 cu.ft to the nearest hundredth.
<h3>What is a Cylindrical figure ?</h3>
A cylinder is a three dimensional figure with two identical circular faces at each end , and a curved surface.
It does not have an edges or vertices.
It is given in the question that
A cylinder with height 14 feet and radius 25 feet.
The volume of a cylinder.
V = π252(14)
The water than can be filled is equal to the volume of the cylinder
V = 11088 cu.ft
There the amount of water that will fill the tank is 11100 cu.ft to the nearest hundredth.

Answer:
<h3>12.56</h3>
Step-by-step explanation:
To get the length of the arc, we are going to use the formula for calculating the circumference of a semicircle.
Circumference of a semi circle = πd/2
Given
Diameter d = 8
π = 3.14
Substitute;
C = 3.14(8)/2
C = 3.14 * 4
C = 12.56
Hence the the length of the arc is 12.56
