Step-by-step explanation:
If we represent this with an equation, we get 3 + |-9x| = 4. Subtract 3 from both sides and we get |-9x| = 1. There are two solutions to this, 1/9 and -1/9, since they both multiply to a number whose absolute value is 1. (-9 * 1/9 = -1, 9 * 1/9 = 1. -1 has an absolute value of 1.)
The volume of a cylinder = pi r^2 h. approximating pi to be 3.14 will give you. 3.14 * (3ft)^2*4ft. this will give you 36 ft^2 times 3.14. this will give you 113.04ft^3
