This is an equation involving x alone, so the most you can do is solve it:
Answer:
78.95cm^2
Step-by-step explanation:
The equation for a cylinder is rπ^2 · h
2π²·4≈78.95
A=132
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=3·10+4·10+5·10+1
2·﹣34+2·(3·4)2+2·(3·5)2﹣44+2·(4·5)2﹣54=132
the slope is -1
m = -1
y2 - y1 y
--------- = ----
x2 - x1 x
= y/x = m
2 - 6
-------
1 - - 3
= -4/4
