Let: eq 1:2x+5y=-55
eq 2:y=3x+6
by substituting eq 2 in eq 1 we get,
2x+5(3x+6)=-55
2x+15x+30+55=0
17x + 85=0
x=-85/17
x=-5
By substituting x value in eq 2,
we have,
y=3(-5)+6=-15+6=-9

Answer:
100 cm³
Step-by-step explanation:
If you use 3 for π, then the factors of 3 cancel in the formula for volume, and you have ...
V = r²h
The radius is half the diameter, so is (10 cm)/2 = 5 cm. Filling in the given values, you find the volume to be ...
V = (5 cm)²(4 cm) = 100 cm³
