The volume of a sphere with radius r is \frac{4}{3}\pi r^3. If the radius is multiplied by a constant k, then the new volume is \frac{4}{3} \pi (kr)^3, which is equal to k^3 \cdot \frac{4}{3} \pi r^3. This means that the volume of the sphere is multiplied by k^3.

a. If the radius is doubled, the volume is multiplied by 8

b. If the radius is tripled, the volume is multiplied by 27

c. if the radius is quadrupled, the volume is multiplied by 64

What is the current yield on a 3 year bond with 10% annual coupons, a par value of 100, and a current price of 107.87?
hichkok12 [17]

The current yield of the bond is 9.27%.

What is current yield?

Current yield is the bond rate of return computed as the annual coupon divided by the current price of the bond

The annual coupon is the coupon rate of 10% multiplied by the bond's par value of 100

annual coupon=10%*100

annual coupon=10

current bond price=107.87

current yield=annual coupon/current bond price

current yield=10/107.87

current yield=9.27%
