b.) Find the Surface Area and volume of the right cylinder. Round your answer two decimal places. T Surface Area: 6 Volume: 12 m​

it has to be a.

b. b < 1 might be the correct answer

step-by-step explanation:

reee

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
