1) 78.5/pi = 25
radius = 5
The one 5 digits away from that coordinate is (2,-1)
2) This question is area, not perimeter. The width and length has to be added by 4 because of 2 feet on both sides.
9*10 = 90 - 30 = 60
3) 25pi according to pythagorean theorem.
Answer:
Part a) List of even vertices: K,L,M,O
List of odd vertices: J,N
Part b) Adjacent to K : J and L
Part c) Degree of L = 4
Step-by-step explanation:
To find the degree of a vertex, simply count the number of segments that end up in that particular vertex. You may even draw a little circle around each vertex to visualize the segments that go through it to reach the vertex.
If the number of segments is an odd number, the vertex is odd.
If the number of segments is even, the vertex is even.
See below the list of degrees of the vertices in your example and their degrees:
J (3)
K (2)
L (4)
M (2)
N (3)
O (2)
The last question now is also answered since the degree of (number of segments ending in) vertex L is 4.
