Calculate the circumference of the two semi circles, which equals a full circle. Then add the two sides of the track.
Circumference is pi x diameter = 3.14 x 22.8 = 71.592, so, you would need to add 71.592 + 49.2 + 49.2 = 169.992 meters, and that would be the length of one lap of the track.
<span>Area of circular metal=πr^2
=3.14 x 3.5 x 3.5 m^2
now,
total cost=area x rate
=3.14 x 3.5 x 3.5 x 3.25 $
=125.01 $</span>
Answer:

Step-by-step explanation:
Answer:
Solve the equation for s by finding a , b , and c of the quadratic then applying the quadratic formula.
s

2
Double roots
Because the cos theta < 0 then theta must be an obtuse angle
so a^2 + b^2 < a^2
C
