Answer:
11 in.²
Step-by-step explanation:
you can divide the shape into 2 rectangles and then you solve for the 2 rectangles and then you add them up.
Answer:
The volume increases at a rate of 
Step-by-step explanation:
The rate of change of the radius with respect to time is 4 mm / s.
So:

Now we must find a relationship between the volume of a sphere and its radius.
The equation of the volume of a sphere is:

So:

The diameter of the sphere is 100 mm. Therefore its radius is 100/2 = 50 mm.
So:

The volume increases at a rate of :
40000 π mm ^ 3 / s = 125663.71 mm^3/s
Answer:
4x -4y
Step-by-step explanation:
5(x-y)-(x-y)
Distribute
5x -5y - x +y
Combine like terms
5x -x -5y +y
4x -4y
