A sample of a radioactive isotope had an initial mass of 200 mg in the year 2000 and decays exponentially over time. A measurement in the year 2004 found that the sample's mass had decayed to 70 mg. What would be the expected mass of the sample in the year 2006, to the nearest whole number?

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
