The volume of the cube is 54.87 but rounded to the nearest tenth is 54.9
The exact volume of the cylinder is 1770.28 but rounded is 1770.29 and the approximate volume of the cylinder is 1769.36
Y=2(-1)^2-6(-1)+3
y=2+6+3
y=8+3
y=11
36;
the square root and the square cancel out, or you can work it out and say
((36)^1/2)^2 = (6)^2= 36
