To the nearest 100th feet, find the volume of a hollow cylinder having inner radius = 150 in, outer radius = 170 in and height = 220 in. (Use T = 3.14)

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply
