Roman mixes 12 liters of 8% acid solution with a 20% acid solution, which results in a 16% acid solution. find the number of liters of 20% acid solution in the new mixture. construct a table to organize the information, and show all of your work to solve the problem

it’s supposed to be -4+45=41

step-by-step explanation:

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
