Not so much interested in the answer, but the processes/steps in which to do it. Preferably translatable to excel terms, but I'm not picky.

1.What is the price of a bond which has a coupon rate of 6.375%, pays coupons semi-annually, has a term to maturity of exactly 11 years and has a yield to maturity of 3.866%?

2.If the clean price of a bond is $1,022.50, what is the dirty price of the bond assuming that the most recent interest payment was on 11/25/16 in the amount of $37.50. Interest is paid semi-annually and the next interest payment is 5/25/17. Assume that the day you are doing your calculation for accrued interest is 2/9/17.

3.What is the yield to call for a bond that is currently priced at $866, has 10 years to maturity, has 6 years to first call, has a call premium of 1%, and pays annual coupon payments of $45?
