The answer is the second option, increase (1,infinity) and decrease (negative infinity,1)
Look at the x axis, not y

Answer:
<u>31.85 square feet</u>
Step-by-step explanation:
Finding the radius :
- C = 2πr
- 20 = 2πr
- r = 20/2π
- r = 10/π
Substituting in the area formula :
- A = πr²
- A = π × 10/π x 10/π
- A = 100/π
- A = 100/3.14
- A = <u>31.85 square feet</u>
<h3>
Answer: 60 degrees</h3>
Reason:
There are 6 angles shown. If they are all the same measure, then they must be 360/6 = 60 degrees each. This is because the angles all glue together to form a full 360 degree rotation. There are no gaps or overlaps.
No able engles? Don’t know if i spelt that right but
