292in^3
3x6x10=180 because I’ve split the shape in half
7x4x4=112
180+112=292
Her next step is to repeat the last process of drawing those two arcs. However, they will be mirrored since she swapped endpoints.
Check out the diagram below. Figure 1 is what she already has. Figure 2 is what happens after completing the next step. The red and blue arcs intersect to help form the endpoints of the perpendicular bisector. I used GeoGebra to make the diagrams.
If you're talking about 607 without decimals, then 0. Because 607 is greater than 48.
124.48 because you can just multiply the number by two.
