Archaeologists have discovered the legendary Golden Igloo of the Pribiloff Islands, a structure consisting of a
halfspherical shell with an inner diameter of 1.25 m and an out diameter of 1.45 m. What is the value of this antiquity,
given that gold currently sells for $1,263/ounce and has a density of 19.3 g/cm3? (Note that 1 ounce = 31.1034768 g)
Answers: 1
: is the inner volume
: is the inner radius = 1.25/2 = 0.625 m
: is the outer volume
: is the outer radius = 1.45/2 = 0.725 m![V_{T} = \frac{2}{3}\pi r_{o}^{3} - \frac{2}{3}\pi r_{i}^{3} = \frac{2}{3}\pi [(0.725 m)^{3} - (0.625 m)^{3}] = 0.29 m^{3}](/tpl/images/1138/7675/b200b.png)

Listenbase your answer to the question on the information below. nuclear radiation is harmful to living cells, particularly to fast-growing cells, such as cancer cells and blood cells. an external beam of the radiation emitted from a radioisotope can be directed on a small area of a person to destroy cancer cells within the body. cobalt-60 is an artificially produced radioisotope that emits gamma rays and beta particles. one hospital keeps a 100.0-gram sample of cobalt-60 in an appropriate, secure storage container for future cancer treatment. which choice represents the correct product for the beta decay of the co-60? fe-60ni-60fe-61ni-61
