Answer:
B 6.3
Step-by-step explanation:
r = 8
l = 2*3.14*r
l = 50.24
s=l/360*45
s≈6.3
Answer:
8 triangles
Step-by-step explanation:
I took this question to mean that we have the lengths, 2, 6, and 7 and have multiple copies of them. Using these lengths, what are all of the triangles that can be made?
2x2x2
6x6x6
7x7x7
2x6x7
6x6x7
6x7x7
2x6x6
2x7x7
2x2x6 and 2x2x7 don’t make a triangle.
So, 8 triangles can be made.

Hence, the distance between (7,8) and (-8,0) is:17
explanation: (a,b)=(7,8) and (c,d)=(-8,0)
8+12=20
20+12=32
Just keep adding by 12
