Non proportional it should be
If unrounded the answer would be 607.5 men but if rounded it would be 608 men
Answer:
11.33 in. to the nearest hundredth.
Step-by-step explanation:
The perimeter of the shaded area = length of the 2 straight lines + the length of the 2 arcs = 4 + length of the 2 arcs.
Calculate the length of the outer arc:
This equals (30 / 360) * perimeter of the largest circle
= 1/12 * 2 π * 8
= 4/3 π in.
The inner circle has a radius of 8 - 2 = 6 ins
so the length of the inner arc
= 1/12 * π * 2 * 6
= π in.
So the perimeter of the shaded region = 4 + 4/3 π + π
= 4 + 7π/3
= 11.33 in.
Answer:
Step-by-step explanation:
<u>Corresponding side have same ratio:</u>
- 55/121 = 5/11 (divide by 11)
- 40/88 = 5/11 (divide by 8)
- 30/66 = 5/11 (divide by 6)
The similarity ratio or the scale factor of the larger triangle to the smaller is 5/11
