The formula for finding the approximate volume of a cylinder is v=3.14r^2h where r is the radius and h is the height. The height of a cylinder is 19.35 cm and the approximate volume is 3400cm^3. Find the radius of the cylinder to the nearest hundredth of a centimeter.

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
