What are the answers to these quesions?

An open pit is dug in the range of the summit of Mount Buffalo. There will be 550 feet wide and 290 feet deep. Based on a sampling of the region, experts predict the company will be able to recover an average of approximately 0.115 ounces of gold per ton ore and barren. The mining company estimates the total cost of production is 80 million. (Take the shape of the mouth is a perfect cone.) 12.What is the volume ore and dispose of waste during mining? 13.How many ounces of gold if the company expected to recover from this mine? (Assume that one ton equals 10 cubic feet). 14.Si the price of gold is $ 375 per ounce, what is the estimated value of gold extracted from this mine? What benefit would the company that hypothesis that the projected cost of production does not change?

12. V = (1 / 3) pi * r ^ 2 * h <— formula for the volume of a cone = (1 / 3) pi * 275 ^ 2 * 290 = 22966351.2947 From 13 cubic feet. First the answer to 12 divided by 10 to obtain the number of tons: Weight = 2296635.12947 tonnes multiplied by 115 to find the total number of ounces of gold: Gold 264,113.039889 ounces = 14. Median = 264113.039889 * 375 = 99,042,389.96 $ profit / loss = 99,042,389.96 to $ 80,000,000 = 19,042,389.96
