Answer:
1,256 dm^2 and 400π dm^2
Step-by-step explanation:
The circumference is equal to 2pi times the radius. So 40pi=2pi times the radius so the radius is 20. The area of a circle is pi times the radius squared or 400pi and if using 3.14 for pi this would be 1,256 dm^2
Considering 1.824 (2 being hundredth) it would mean that this is 1.82 <span />
The correct answer is B)
-3 < y ≤ 3
You can tell this by looking at the graph. The lowest that it goes is -3. You'll also note that the -3 has an open circle, which means that it isn't includes and thus needs a <.
The highest it goes it 3. You'll note that it has a closed circle, which means it is included and needs a ≤.
Answer:
B
Step-by-step explanation:
B could be an isosceles triangle
A can't because it has 4 sides
C can't because it has 2 sides
The answer to this question is 13.
