Answer:
40.56ft
Step-by-step explanation:
We add 8 to 10 and 10 to get 28. After this we have to find the circumference of the half circle. To do this we use C=2πr to get 25.12 which we then divide by 2 to get 12.56. We add this to the old total of 28 to get the new total of 40.56. Hope this helps :)
