Firstly triangle OAB is equilateral so R = AB =OA = 8 in
MES (ARC AB) = R x Ф (in Radian). Note that 60° =π/3
MES (ARC AB) = 8 x π/3 (D)
Answer:
YES
Step-by-step explanation:
As x increases by 3 each time, y also increases by a steady number each time, which is 6. This means that x and y are in a proportional relationship with a 1:2 ratio.
