Answer:
Step-by-step explanation:
volume of cone v=1/3πr²h
volume of cylinder V=πr²h
V=3v
volume of cylinder=3×222=666 cubic cm.
8 - 15 means subtract the positive number 15 from 8.
8 - 15 = 8 + (-15) = -7
8 - (-15) means subtract the negative number -15 from 8.
Subtracting a negative number is the same as adding a positive number.
8 - (-15) = 8 + 15 = 23
8 - 15 = -7, and 8 - (-15) = 23. The expressions mean different operations and have different answers.
Using conversion of units, it is found that Dylan needs another 1.29 ounces of cheese.
----------------------------
- The conversion of units are applied using a rule of three.
- Each gram has 0.035274 ounces. How many ounces are there in 150 grams?
1 gram - 0.035274 ounces
150 grams - x ounces
Applying cross multiplication:
----------------------------
- Dylan has 4 ounces of cheddar cheese.
- He needs 5.29 ounces.
- Thus, he needs another 5.29 - 4 = 1.29 ounces.
