HELP HELP ME PLEASE!!!
Harman [31]
Use the cone formula:
V =  \pi r^{2}  \frac{h}{3}
And so:
Area =  \pi * 150^{2} *  \frac{240}{3} = 5654866.7 inches^{2}
5654866.7 / 12000 = 471,
So the answer is 471 weeks.

Hope this helps.

2. Total number of persons

Look at the intersection of the totals for the columns and the rows: 500

3. Number of persons that consume 1,500 to 2,000 calories in a day

Look at the total for the column 1,500 to 2,000 calories per day: 250

4. Probability that a person consumes 1,500 to 2,000 calories in a day, P

  • P = number of persons that consume 1,500 to 2,000 calories / total number of persons

  • P = 250 / 500 = 0.50 ↔ option D.
