Answer:
D
Step-by-step explanation:
The area and the radius of a sphere are related by the formula:
 A=4πr^2
Let’s say this is A1 and r1
Now the radius is tripled. This means r2 = 3r1
The new area thus becomes: A = 4 * (3r)^2 * π = 36πr^2
Comparing A1 and A2 , we can see that A2 = 9A1

Answer:
   $2070.14
Step-by-step explanation:
Credit card terms vary, as do methods of computing interest and new balance. Here, we'll assume that no payment has been made (<em>in violation of the terms of the credit card</em>), and that the finance charge is only applied to the previous balance.
The finance charge is ...
   $1853.68 × 0.249 ÷ 12 = $38.46 . . . . . . . the monthly rate is 0.249÷12
Then the new balance will be the sum of the previous balance, finance charge, and new transaction(s):
   $1853.68 +38.46 + 178.00 = $2070.14
_____
<em>Comment on lack of payment</em>
Because no payment has been made, there may also be a late-payment charge added to the balance.
