I believe that it is 2 because you have 1 line with 3 plots meaning 1.2.3 and the dots could represent rays.
hope this helps otherwise let me know.

Answer:
16π
Step-by-step explanation:
Circumference = 2πr. Since the radius, r, is unknown, we can get it from the area.
Area = πr² = 64π ;
Divide both sides by π. We are left with
r² = 64; To find r, take square root of both sides
Therefore, r = √64 = 8m;
Circumference = 2×π×8 = 16πm
Answer:side one is 8cm
Side 2 is 8cm
Side 3 is 15 cm
Step-by-step explanation:
The perimeter of a shape is the distance around the shape. The perimeter of a triangle is the sum of the sides of the triangle.
Let x represent the length of side one and side 2. Since they have equal length, the sum of their length is x + x = 2x cm
Side three is one cm shorter then twice the length of side one. This means that the length of side three would be 2x - 1
The perimeter of a triangle is 31cm. Therefore,
2x + 2x - 1 = 31
4x - 1 = 31
4x = 31 + 1 = 32
x = 32/4 = 8 cm
Side three = 2×8 - 1 = 16 - 1 = 15
