Step-by-step explanation:

radius is 1.5 height is 4 so

V=1/3nr^2h

V=1/3n(1.5)^2(4)

V=1/3n(2.25)(4)

V=9.42

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

thats not a system of equations, that is a solution
