Factor this expression completely
18xy - 9wy - 12y

A. 3y(6x-3w-4)

B. 3(6xy-3wy-4y)

C. -3y(-6x+3w+4)

D. 9y(2x-3w-12)

3y(6x-3w-4)

Step-by-step explanation:

18xy - 9wy - 12y

18xy = 3*3*2*x*y

9wy = 3*3*w*y

12y = 3*2*2*y

We can factor out a 3 and a y

3*3*2*x*y - 3*3*w*y - 3*2*2*y

3y(3*2*x - 3*w - 2*2)

3y(6x-3w-4)

77

step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
