The curved parts of the figure are arcs centered at points A bad C. What is the approximate length of boundary ABCD? Use the value pie= 3.14, and round to one decimal place. A 17.8 B 23.8 C 23.1 D 28.1

Plot the points (0,6), (3,15.8), and (9.5,0) using the graphing tool, and find the function

What is the best approximation for the area of a circle with a radius of 4 m ? use 3.14 to approximate pi

The figure shows triangle def and line segment bc, which is parallel to ef: triangle def has a point b on side de and point c on side df. the line bc is parallel to the line ef. part a: is triangle def similar to triangle dbc? explain using what you know about triangle similarity. part b: which line segment on triangle dbc corresponds to line segment ef? explain your answer. part c: which angle on triangle dbc corresponds to angle f? explain your answer. asap
