The distance between (5, 2) and (2,-2) is 5 units
Check the picture below.
so the lunchbox is really a semi-circle with a radius of 3, sitting on top of a square of 6x6, with a lenght of 10.
the volume of the lunchbox then will be the area of the semi-circle and square times the length.
2x + y - 4 = 0
We need to first rearrange this so y is the subject
Can you do that or u need help
