Circumference = r * 2 * pi
Circumference of track 1 is 376.8
Y = 3.5x
24= 3.5x
the train will be ride 6 times each day
and there are 7 days in a week
so multiply 6 and 7
=42
First you want to get h alone so you divide 2<span>π</span>r by s so your answer would be
h=S/2πr
Add them all up, and divide by 10 so 29+38+39+26+29+29+39+77+38+29 which is 33.5
Answer:
624
Step-by-step explanation:
the area of the triangles:
12*10 = 120
120/2 = 60
since there are 2 triangles of the same dimensions that make up the surface area 60 + 60 = 120
area of the rectangles:
13*14 = 182
since there are 2 rectangles of the same dimensions 182 + 182 = 364
The last rectangular:
10*14 = 140
add all areas:
120 + 364 + 140 = 624
