First we need to calculate the mass of golden sphere.
r=0.5d=0.625 in. = 1,5875 cm.
v=343.14r3=343.14×1.58753=16.749cm3
m=vρ=16.749×19.3=323.2557.8g
cost/g=28.35850=29.98/g
price of golden sphere = 181.8×29.98=9696.53dollars
Answer: 9696.5 dollars

Hello, There is a mistake in the question. The volume of a sphere is V=(4/3)πr^3, not (3/4)πr^3. The final answer is $9696.53 not $5450.
