Answer:
69.1 cm
Step-by-step explanation:
Circumference of a circle
c = 2πr
Half of that would be a semi-circle
c = πr
c = π * 22
c = 69.115038379
Rounded
69.1 cm
Answer:
w = -1
Step-by-step explanation:
- w-5-4= -8-6w+8w ⇒ simplify
- w - 9 = - 8 + 2w ⇒ add 9 - 2w to both sides
- w - 2w = - 8 + 9 ⇒ simplify
- -w = 1 ⇒ multiply both sides by -1
- w = -1 ⇒ answer
