True!

The surface area of a cylinder is:
SA = 2πr² + 2πrh
r = 1 in
h = 4 in
π = 3.14

SA = 2 * 3.14 * 1² + 2 * 3.14 * 1 * 4
      = 6.28 + 25.12
      = 31.4 in²

Hello!

Throughout this problem, we will add or subtract values from our original balance.

In your checkbook, there was 298.72 dollars, and then you deposited 425.69 dollars. The function you would do is addition.

$298.72 + 425.69 = $724.41

If you wrote a check, then the amount you wrote is removed from your checkbook.

$724.41 - $29.72 - $135.47- $208.28 = $350.94

Then, the bank deducted 5 dollars from your account.

$350.94 - $5.00 = $345.94

This leaves you with $345.94 at the end of the week.

Therefore, your answer is choice C, $345.94.
