Answer:
398.21 m
Step-by-step explanation:
The field inside a running track is made of a rectangle that is 84.39 m long and 73 m wide to gather with a half circle at each end.
So, the radius of each half circle will be 
m.
Therefore, the total distance around the track i.e perimeter of the area covered by the track will be = 2 × Perimeter of each half circle + 2 × Length of the rectangle.
= Perimeter of full circle + 2 × Length of the rectangle.
= 
= 
= 398.21 m.(Answer)

Answer: Choice C. a = 17, b = 6</h3>
Explanation:
A kite is any quadrilateral where we have two pairs of congruent consecutive sides (in contrast to a parallelogram where the opposite sides are congruent). Draw a segment connecting points G and J. Triangle GHJ is congruent to triangle GFJ. We'll use the fact that GH = GF, and also FJ = HJ
So,
GH = GF
2a-4 = 30
2a = 30+4
2a = 34
a = 34/2
a = 17
and
FJ = HJ
3b+6 = 24
3b = 24-6
3b = 18
b = 18/3
b = 6
Answer:
14.4km
Step-by-step explanation:
<h2>Speed = distance / time </h2>
- speed = 4.8 km/h
- time = 3 hrs
- distance = ?
Distance = speed * time
Distance = 4.8 * 3 = 14.4km
Answer:
None of these.
Step-by-step explanation:
The sector angle is not given, therefore no conclusions about the choices involving points D,E and A,B with respect to each other, and C, F can be made.
Answer:
9
Step-by-step explanation:
I used tan but there's probably an easier way to do this but 4*tan(20)=8.94 then round it up to 9
