D. (I used 3.14 as pi so my answer was a little off so I just went with the one closest to my answer)
Answer:
The answer is 10.6 (I'm sorry if it's wrong)
Step-by-step explanation:
found out what D and B is (they both are 4 I think) then add 10 with 8 then divide 120 with 18 which is 6.6 then add what D is and then I got 10.6
