Answer:
To find the circumference, you multiply the radius by 2 and then multiply that by pi (or π). The equation is 2πr
In this case, we already have the radius x 2, which is the diameter. For this circle, the diameter is 12 cm.
The next step is to multiply the diameter, 12 cm, by pi (π is about equal to 3.14)
12 x π ≈ 37.698 cm or 38 cm rounded to the nearest whole number

Step-by-step explanation:
Sin 61 = 47/X
(X=AB)
X = 53.73764119
Answer:
(8x + 1)° + ( 4x+11)° = 180° (linear pair )
8x +1 + 4x +11 = 180
8x + 4x + 1 + 11 = 180
12x + 12 = 180
12x = 180 - 12
12x = 168
x= 168/12
x = 14
