To answer this question you will need to find the total volume the rain barrel can hold. Then find the volume of water that it is currently holding.
Subtract these two amounts to find the total amount of water or can still hold.
Then convert this amount to gallons.
1. V = pi x r^2 x h
3.14 x 1.25^2 x 3.5
V = 17.17 cubic feet
2. Same formula
3.14 x 1.25^2 x 1.5
V = 7.36 cubic feet
3. 17.17 - 7.36 = 9.81 cubic feet
4. 9.81 x 7.5 = 73.575 gallons or approximately 74 gallons.
Answer:
Step-by-step explanation:
When converting mixed numbers (such as the one above), to improper fractions, we must first multiply the whole number by the denominator:
Then, add the numerator the the product:
Now, put the sum over the denominator to get your solution:
-
To check your work, you can convert the improper fraction to a mixed number to make sure you will end up with .
Divide into :
with a remainder of
Put the remainder over the denominator:
Therefore, our solution is correct!
