Heyyy me again. need with this problem.

y=4

Step-by-step explanation:

1.- subtract 1/4 y from both sides

2.- add 12 to both sides

3.-divide both sides by 2

y= 4

Step-by-step explanation:

first change 9/4 and 1/4 in decimals

9/4 = 2.25

1/4 = .25

2.25y - 12 = .25y - 4

Then subtract .25y on both sides. Your left with:

2y - 12 = -4

Add 12 on both sides. Your left with:

2y = 8

Divide 2 on both sides

y= 4

d

step-by-step explanation:

d

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 !
