Blababa [14]

Answer:

8.5 inches

Step-by-step explanation:

First let's find the time t when the depth of the snow is 7 inches.

To do this, we just need to use the value of D = 7 then find the value of t:

7 = 1.5t + 4

1.5t = 3

t = 2\ hours

We want to find the depth of snow one hour from now, so we just need to use the value of t = 3 to calculate D:

D = 1.5*3 + 4

D = 4.5 + 4 = 8.5\ inches

The depth of snow one hour from now will be 8.5 inches.

Nastasia [14]

Volume of a cylinder = πr²h

where,

r is the radius of the cylinder

h is the height of the cylinder

Area of the rectangle = length X breadth

In that case, the breath of the rectangle will become the diameter of the cylinder and the length will become the height of the cylinder.
