Answer: 1211.6585 years
<u>Step-by-step explanation:</u>
The equation for exponential growth is:
- P: final population
- P₀: initial population
- k: rate of decay (or growth)
- t: time
Use the half life information to find k:
Next, input the information (65% decayed = 35% remaining) and the k-value to find your answer.
V solid = π * 
* 13 / 3 + π * * 2 = 3.14 * 25 *13 / 3 + 3.14 * 50 = 340.16 + 157 = 497.16 ≈ 497.20 cubic centimeters;
