The circumference of circle is 20.096 units
<em><u>Solution:</u></em>
Given that circle has a diameter  with endpoints at (10, 8)  and (5, 4)
To get the diameter, find the distance between the end points
<em><u>The distance between two points is given by formula;</u></em>

Here the points are (10, 8)  and (5, 4)

Substituting the values we get,


Thus the diameter is 6.4 units
<em><u>The  circumference of the circle is given by formula:</u></em>

Where "d" is the diameter of circle

Thus circumference of circle is 20.096 units
 
        
             
        
        
        
Answer:
Ellen gave 24 inches of her ribbon to the friend.
Explanation:
The total length of ribbon Ellen has = 20 feet
Used to make pillows = 12 feet
Remaining ribbon = 20-12 = 8 feet
Given to her friend = 1/4 
1/4 of 8 = 1/4 × 8 = 2 feet
so she gave 2 feet of ribbon to her friend.
- As there are 12 inches in 1 foot.
so
2 feet in inches = 24 inches
Therefore, Ellen gave 24 inches of her ribbon to the friend.
 
        
             
        
        
        
Answer: b. Orchid mantises tend to be advantaged in habitats that remain constant; the rain forest habitat is likely to shift because of global climate change.
Explanation:
The orchid mantis is a predator in South East Asia that camouflages itself as an orchid to catch its prey.
While the tropical cockroach is a more hardy specie, the optimum habitat for orchid mantises is one with limited variation in temperature, moisture and humidity. Therefore, as temperatures increase and climate change results in severe weather changes, it will lead to adverse effects on orchid mantises.
