The formula for the volume of a cylinder is V = πr^2h
From the problem r = 4, h = 21 and you use 3.14 for pi
Volume = 3.14 * 4^2 * 21
Volume = 1055.04 cubic feet
the answear us true im preety sure
-36x<8 divide both sides by -36 (reversing the direction of the inequality sign because of division by a negative number)
x>-8/36 the largest common factor of 8 and 36 is 4 so divide numerator and denominator by this factor, 8 to simplify the fraction
x>-2/9 or in proper notation, x=(-2/9, +oo)
