The differences between he numbers are 19, so the answer is 58 + 19 = 71
so hmmm let's get the area of the whole hexagon, and then get the area of the circle inside it, then <u>subtract the area of the circle from that of the hexagon's</u>, what's leftover is what we didn't subtract, namely the shaded part.

Answer:
The point (-8,7) is the reflection of the point (8,7)
Answer:
34 boys
Step-by-step explanation:
72 students
G-19:B-17 Ratio
19 + 17 = 36
72/36 = 2
19 x 2 = 38
38 girls
17 x 2 = 34
34 boys
Answer:
√36 = 6
a^2 + b^2 = c^2
6^2 + 6^2 = c^2
36 + 36 = c^2
72 = c^2
√72 = c
2 36
2 18
2 9
3 3
6√2 = c
6√2 = (estimate rounded up, 8.49)
