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

It has 97 amounts.

Numbers between 42-140
The correct answer is: "The value of the 5 in 50.8 is 1,000 times the value of the 5 in 18.35."
Step-by-step explanation:
When numbers are considered, their position or place value matters a lot.
When a decimal number is written, moving left from the decimal point the place value increases ten times and while moving to the right the place value decreases 10 times.
Given two numbers are:
50.8 and 18.35
In order to compare the 5 in both numbers we have to find the place value of 55 in both numbers.
So,
<u>In 50.8:</u>
The place value of 5 in 50.8 is: 50
<u>In 18.35:</u>
The place value of 5 will be: 5/100
To compare the values, we will divide the larger place value by smaller place value

Hence,
The correct answer is: "The value of the 5 in 50.8 is 1,000 times the value of the 5 in 18.35."
