Answer:
25π
Step-by-step explanation:
1) for whole circuit: A=π*r², where r - radius of the given circle;
2) for a quater of the circuit: A=πr²/4;
3) finally, A=π*100/4=25π.
Answer:
440 miles
Step-by-step explanation:
Perimeter of a quadrilateral, P :
P = a + b + c + d
Which is the sum of all the sides ;
From the diagram attached ;
Perimeter of the quadrilateral is :
(170 + 160 + 80 + 30) = 440 miles
Answer: ALL ANSWERS BELOW
1.) 1:4 ratio
2.) 100
3.) 125
4.) perimeter multiplied by 4 for every 1 toothpick as side length. + Side length always smaller than perimeter.

Answer:
see below
Step-by-step explanation:
a bearing is the angle in degrees measured clockwise from north.
Triangle ABC is a right triangle
Tan C = opp side / hyp
tan C = AB / CA
tan C = 30/30
tan C = 1
taking the inverse tan
tan ^ -1 tan C = tan ^ -1 ( 1)
C = 45 degrees
This is 90+45 degrees from North
135 degrees from north
Tan B = opp side / hyp
tan B = AD/BA
tan B = 45/30
tan B = 3/2
taking the inverse tan
tan ^ -1 tan B = tan ^ -1 ( 3/2)
D = 56.30993247
Add 180 degrees
180+56.30993247
236.3099325 from north
