If you'd graph this function, you'd see that it's positive on [-1.5,0], and that it's possible to inscribe 3 rectangles on the intervals [-1.5,-1), (-1,-0.5), (-0.5, 1].
The width of each rect. is 1/2.
The heights of the 3 inscribed rect. are {-2.25+6, -1+6, -.25+6} = {3.75,5,5.75}.
The areas of these 3 inscribed rect. are (1/2)*{3.75,5,5.75}, which come out to:
{1.875, 2.5, 2.875}
Add these three areas together; you sum will represent the approx. area under the given curve on the given interval: 1.875+2.5+2.875 = ?

Answer:
15.4
Step-by-step explanation:
15276 = 4/3 πr³
11457 = πr³
3646.88 = r³
15.4 = r
1) 12 cm
2) 38
3) 20
4) 40
Each cm is equivalent to 12.5m. So what you can do I just divide all of them by 12.5 to get the answers above.
