Decay expression is stated as follows:
N(t) = N(o)e^(-0.693t/t1/2)
N(t) = Quantity remaining after time, t; N(o) = Initial quantity, t = time, t1/2 = Half life
Therefore,
N(6.55) = 2*e^(-0.693*6.55/5.2) = 0.835 g
Answer:
415.48 or 132.25 pi cm
Step-by-step explanation:
23 divided by 2 is 11.5 so that is the radius. Then you multiply the radius by pi. Or you can do 11.5 x 11.5 if you are trying to find the solution without pi.
