There will be a 25 grams left after 3240 years.
The half-life of Radium-226 is 1620 years. If we divide 3240 by 1620 the answer is 2. So that means the amount of Radium-226 will divide in half twice.
100 / 2 = 50 / 2 = 25
Answer:
18
Step-by-step explanation:
1,017.36 is the area of the circle and you need to find the radius
area formula : 3.14rsquared
so the formula you are going to solve for your answer is 3.14rsquared=1,017.36
divide by 3.14
rsquared = 324
un square it to get you radius which is 18
you didnt clarify whether you wanted radisu or diameter so ill give both
R: 18
D:36
