Rise over run is -2/4 or simplified as -1/2
The second one is
Answer:
I hope this helps you
Step-by-step explanation:
Area = Base × Height
= 1.8m × 2.5m
= 4.5m^2
now, let's recall Cavalieri's Principle, "solids with equal altitudes and cross-sectional areas at each height, have the same volume".
so, even though this cylinder is slanted, it has the same cross-sectional area as a cylinder that's straight-up, whose altitude is h = 5, and radius r = 4.
