Step-by-step explanation:
The cost of the bond was 90/100 times $5,000, that is, $4,500 total.
<span>The annual interest is 5% of $5,000, that is, $250. </span>
<span>The current yield is 5% divided by (90/100), that is 5.555%; round to 5.6% as instructed. </span>
<span>The yield that real bond buyers would be more interested in is the yield to maturity, but this cannot be calculated without knowing the term (number of years). If it's a short term bond that will pay you back $5,000 in just a few years, that would add several percent to the yield, but if it's a 15-year bond the growth of the $4,500 to $5,000 adds only a fraction of 1% to the yield.</span>
The diameter of a circle is calculated by using the formula D=r2pi so plug in the known values to find r=2/pi. Next plug r into the area of a circle formula(A=r^2pi) do so and get 4/pi
