Hi there! In order to find the simple interest rate of the bonds, we have to divide the received payment by the bonds invested in them. 504/8,000 is 0.063. This number is in decimal form, but let's multiply by 100 to get the percentage of the number. 0.063 * 100 is 6.3. There. The simple interest rate of the bonds is 6.3%.
These are chords of a circle, and the equation to solve for any unknowns is to multiply the 2 sections of one chord and set it equal to the mutiplied 2 sections of the other chord. In our case that will look like this: x * 15 = 6 * 5. That's 15x=30. x = 2
Use the equation 2πr (so it would be 2π5 or 31.4)
