The length of a 180° arc of a unit circle is π ≈ 3.14 units.
Step-by-step explanation:
Use your knowledge of the circumference of a circle (the length full around) and the fact that there are 360° in the central angle of a full circle. The distance around is proportional to the angle, so an arc of measure 180° will have a length equal to
X + x + 24 = 58 x = (58-24)/2=17 the first number is 17 and the second number is the sum of 17 and 28. Finding it has been left as an exercise for the reader.
Since this number has a decimal. Break the answer apart. 2.75•2=$5.50. That would be for two pounds. For another additional 0.5 pounds, you would divide $2.75/2= 1.375. This would be rounded up to 1.38. Now you add 5.50+1.38=$6.88
