The correct answer is: [C]: " $4290.00 " .
_______________________________________
Explanation:
_________________________________________
Given: principal, "P": equals: $14,300 ;
rate, "r" : equals: 7.5 % = 7.5 / 100 = 0.075 ;
time, "t" (in years): equals: 4 ;
_________________________________________
What is the interest, "i" ?
_________________________________________
Note: The formula: i = P * r * t .
_________________________________________
So, we plug in our given values for "P", "r", and "t", and solve for "i" (interest).
__________________________
i = ($14,300) *(0.075) * (4) ;
i = $1,490 ; which is answer choice: [C]: " $4290.00 " .

Volume = πr²h
---------------------------------------
Find Volume of one tank
---------------------------------------
Volume of 1 tank = πr²h
Volume of 1 tank = 3.14 x 6² x 12
Volume of 1 tank = 678.24 ft³
---------------------------------------
Find Volume of 5 tanks
---------------------------------------
Volume of 1 tank = 678.24
Volume of 5 tanks = 678.24 x 5
Volume of 5 tanks = 3391.2 ft³

Step-by-step explanation:
So basically you need to multiply 3000x4000 in two ways? If so you can use basic multiplication and an area model
Answer:
Volume: 
Ratio: 
Step-by-step explanation:
First of all, we need to find the volume of the hemispherical tank.
The volume of a sphere is given by:
where
r is the radius of the sphere
V is the volume
Here, we have a hemispherical tank: a hemisphere is exactly a sphere cut in a half, so its volume is half that of the sphere:
Now we want to find the ratio between the volume of the hemisphere and its surface area.
The surface area of a sphere is
For a hemisphere, the area of the curved part of the surface is therefore half of this value, so 
. Moreover, we have to add the surface of the base, which is 
. So the total surface area of the hemispherical tank is
Therefore, the ratio betwen the volume and the surface area of the hemisphere is
