Answer:
15% decrease
Step-by-step explanation:
First - 322,000
Years later - 273,700
Therefore, (322000 - 273700)/322000 = 0.15
0.15 * 100 = 15%

Step-by-step explanation:
<span>The question asks to find how long will it take until to fill the cone if 1413 cm^3 of water goes in it every minute. First we have to find the volume of the cone: V = 1/3 r^2 Pi * h; V = 1/3 * 60^2 * 3.14 * 150 ; V = 1/3 * 3600 * 471; V = 565,200 cm^3. If 1413 cm^3 of water goes every minute into the cone, we have to divide the volume by 1413: 565,200 : 1413 = 400. Answer: It will take 400 minutes. </span>
