Please check the explanation.
Step-by-step explanation:
BLUE PENTAGON
The blue shape represents the Pentagon
The length of the side a = 7
As there are 5 sides.
Thus,
The Perimeter of the Blue Pentagon = P = 5a = 5(7) = 35
Using the formula to determine the area of the Pentagon
Thus,
The Area of the Blue Pentagon =
RED PENTAGON
The red shape represents the Pentagon
The length of the side a = 4
As there are 5 sides.
Thus,
The Perimeter of the Red Pentagon = P = 5a = 5(4) = 20
Using the formula to determine the area of the Pentagon
The Area of the Red Pentagon =
<u><em>Conclusion:</em></u>
The Perimeter of the Blue Pentagon = 35
The Perimeter of the Red Pentagon = 20
Thus, the<u><em> ratio of the perimeter</em></u> is: 35/20 = 7/4
The Area of the Blue Pentagon = 84.3 = 843/10
The Area of the Red Pentagon = 27.5 = 275/10
Thus, the<u><em> ratio of the Area</em></u> is:
Answer:
arc ≈ 5.5 units
Step-by-step explanation:
The arc of the circle is calculated as
arc = circumference of circle × fraction of circle
= 2πr × ( r is the radius )
= 2π × 3.5 ×
=
≈ 5.5 ( to the nearest tenth )
