A?

Your first answer is correct.

None of my answers match your choices in the second problem.

Your third answer is wrong.

Pi only means 3 for us. Not any of the other numbers if that helps.

Because I thought the formula for an area of a circle is π(r)^2

OK. If you're using 3 for pi, then your answer is right. Most people use 3.14 for pi.

To find the area of the Wilson family's game room, we need to calculate the length and width of the game room first. It is mentioned in the question that the game room is 4 feet shorter in both length and width compared to the living room.

The length of the game room would be 25 feet - 4 feet = 21 feet.
The width of the game room would be 18 feet - 4 feet = 14 feet.

Now, we can calculate the area of the game room by multiplying the length and width:
Area = Length x Width
Area = 21 feet x 14 feet
Area = 294 square feet

Therefore, the correct answer is D. 294.

To find the area of the circle with a radius of 8, we can use the formula for the area of a circle, which is:

Area = π(radius)²

Plugging in the given radius of 8, we get:

Area = 3.14 x (8)²
Area = 3.14 x 64
Area ≈ 201.06

The closest option is C. 192.

To calculate the perimeter of a rectangle, we add up all the sides of the rectangle. The perimeter of a rectangle can be found using the formula:

Perimeter = 2(Length) + 2(Width)

Therefore, the correct answer is D. p=2(L)+2(w).
