Henry know that the circumference of a circle is 18 pie inches. What is the area of the circle?
A:36
B:81
C:162
D:324

B: 81π inches

Step-by-step explanation:

The formula for the circumference of a circle is C = πd and the formula for the area of a circle is A = πr²

Plugging in our known values to the circumference formula we have:

Now that we have solved for the radius, we can plug in this value to the area formula:

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

answer:

some responsibilities that come with having a checking account -

1. we have to maintain check register with exactness to avoid checks being returned for insufficient funds which is called bouncing a check.

2. we need to update our check register each time we make a transaction using a convenience card. updating check register will   save   us from   overdrawing of checking account.

3. read the agreement the bank gave you when you signed up for our checking account. this includes all the fees and the minimum balance we need to keep in our account to avoid maintenance charges.  

explanation:

note : -   checking account is a transactional deposit account. we can use it to deposit and withdraw funds. money in a checking account is very liquid. it   can be withdrawn using electronic debits, automated cash machines, or checks among other methods.
