Answer:
the formula represent the correct way is  π(4)^2 (5)
Step-by-step explanation:
The formula that represent the correct way to calculate is given below:
As we know that 
Volume = πr^2 h
where
r denotes the radius i.e. 4 inches 
And, h denotes the height i.e. 5 inches
Now placed these values to the above formula
So, 
= π(4)^2 × 5
= 80π in^3
Hence, the formula represent the correct way is  π(4)^2 (5)
 
        
                    
             
        
        
        
Answer:
The percent increase between getting a high school scholarship and bachelor's degree is <u>59.14%</u>.
Step-by-step explanation:
Given:
High school scholarship is $421.
Bachelor's degree is $670.
Now, to find the percent increase between a high school scholarship and bachelor's degree.
So, we get the amount of increase between a high school scholarship and bachelor's degree.

<em>Thus, the amount of increase = $249</em>.
Now, to get the percent increase between a high school scholarship and bachelor's degree:



Therefore, the percent increase between getting a high school scholarship and bachelor's degree is 59.14%.
