A town accumulated 2 inches of snow and the depth is increasing by 6 inches every hour. A nearby town ha accumulated 9 inches of
Svetach [21]

Answer: it will take 2.33 hours for the snow fall in both of the towns be equal.

Step-by-step explanation:

Let x represent the number of hours that it will take for the snow fall in both of the towns be equal.

A town accumulated 2 inches of snow and the depth is increasing by 6 inches every hour. This means that in x hours, the depth of snow in the town would be

6x + 2

A nearby town has accumulated 9 inches of snow and the depth is increasing by 3 inches every hour. This means that in x hours, the depth of snow in the town would be

3x + 9

For the snow fall in both of the towns be equal, the number of hours would be

6x + 2 = 3x + 9

6x - 3x = 9 - 2

3x = 7

x = 7/3 = 2.33 hours

The volume of a cylinder is given by V = pi r^2h
storchak [24]

Answer:

D.

Step-by-step explanation:

Simply plug in your variables and solve (<em>r </em>= x + 2 and <em>h</em> = 3x + 8):

V = π(x + 2)²(3x + 8)

V = π(x² + 4x + 4)(3x + 8)

V = π(3x³ + 20x² + 44x + 32)

V = 3x³π + 20x²π + 44xπ + 32π
