A. 2025pi in^2
Step-by-step explanation:
If you change a linear dimension by a factor of k, the area changes by a factor of k^2.
The radius changes by a factor of 3. The area changes by a factor of 3^2 which is 9.
9 * 225pi square inches = 2025pi square inches
Answer:
After 25 years both the accounts will have the same balance.
Step-by-step explanation:
Let t years, both the account will have the same balance.
As account A has a beginning balance of $500 and grows by $25 per year.
So, the total balance of account A after t years = 500+25t
Similarly, account B has a beginning balance of $750 and grows by $15 per year.
So, the total balance of account A after t years = 750+15t
As both the accounts has the same balance, so
500+25t= 750+15t
25t-15t=750-500
10t=250
t=250/10
t=25 years
Hence, after 25 years both the accounts will have the same balance.
