Question says that there are two type of pans.
First pan has diameter of 9 inches.
Second pan has dimension 8 inches by 11 inches. Which means second pan is rectangular.
It seems you missed few parts of the question like what we have to do with it. I searched for similar question on internet and found that they are finding surface area of the both pans so i will tell you how to find that.
Radius of the circular pan = diameter/2 = 9/2 = 4.5 inches
Then surface area of the first (circular) pan = \pi r^2 = 3.14 *4.5^2 = 63.585 square inches.
Now surface area of second (rectangular) pan is given by formula of area of rectangle
Area = Length * width = 8*11= 88 square inches.
The volume of the shape
We have a cylinder that is cut into two. Its external radius is 5ft, while its internal radius is 4ft.
External radius = internal radius + thickness

Internal radius = 4ft (given)
Recall that the volume(V) of a full cylinder is:

Since the cylinder is cut into two, the volume(V) is:

height (h) = 12ft (given)
The volume of the shape:
Sales increased 50% last year, from $5,000 to $10,000. When sales dropped from $10,000 to $5,000 this year, sales decreased 50%
