If y is decreased by 30, then you are saying y-30.
The correct simplification will be: (b) ab²

Here we will use the property of exponents for division of two exponential terms with same bases. The original property is : 
It means if the bases are same , then we will just subtract the exponents while dividing two terms.
Using this property:

and 
So, 
Answer:
11144850.566161 centimeters3
Step-by-step explanation:
Volume = πr2h
= π×121.052×242.1
= 3547516.11525π
= 11144850.566161 centimeters3
