Answer:
41.9
Explanation:
Arc Length = x/360 * 2πr
x = angle of the arc
r = 10
Length of Blue Arc = 240/360 * 2πr
Length of Blue Arc = 2/3 * 2πr
Length of Blue Arc = 2/3 * 2π(10)
Length of Blue Arc = 2/3 * 20π
Length of Blue Arc = 40/3 * π
Length of Blue Arc = 41.8879020479...
to the nearest tenth = 41.9
