Yes, this is an algebraic expression, and is the simplest possible. Cannot be simplified further, and cannot be factored.
If we know the value of x, we can evaluate it to a number, otherwise, it stays as it is.
Or, perhaps the question is not complete.

Answer:
240 m²
Step-by-step explanation:
The lateral surface area is given by the formula ...
LA = πrs . . . . . cone with radius r and slant height s
The base area is given by the formula ...
BA = πr²
The total surface area is the sum of these:
SA = BA +LA = πr² +πrs = πr(r+s)
The radius is half the diameter, so is 9m/2 = 4.5 m. Then the surface area is ...
SA = π(4.5 m)(4.5 m +12.5 m) = 76.5π m² ≈ 240 m²
First, how much did you spend on the 8 gumdrops at 2 cents a piece?
8 gumdrops at 2 cents a piece is 16 cents
8 gumdrops x 2 cents = 16 cents
So, if you have 16 cents to spend on gumdrops and they are 8 cents a piece, how many can you buy?
16 / 8 = 2
You can buy 2 gumdrops for the same amount of money.
