The area of a circle is pi*(radius)^2.
If the 8 ft is the diameter, the area is pi*(4 ft)^2~=50.27 ft^2
(ft^2 is square feet)
240 square feet
The circumference of an 8 ft circle is: 25.1 feet.
If you are looking for the square footage of the room, the height shouldn't make a difference. So the square footage would just be 10 ft x 10 ft = 100 square feet. If you are looking for surface area of all the walls, floor, and ceiling, that would be 100+100+80+80+80+80 = 520 square feet If you're looking for the cubic footage of the room, then you would use all three dimensions. 8ft x 10ft x 10ft = 800 cubic feet.
50.3 square feet for an 8-foot diameter circle.
To convert from square feet to square meters, you can use the conversion factor of 1 square meter = 10.764 square feet. First, calculate the area in square feet by multiplying the length (8 ft) by the width (6 ft) to get 48 square feet. Then, divide the area in square feet by the conversion factor to get the area in square meters: 48 sq ft / 10.764 sq ft = 4.46 square meters. Therefore, an 8 ft by 6 ft area is approximately 4.46 square meters.
Square footage of the room = 14 ft * 8 ft = 14*8 sq ft = 112 sq ft.
For square footage (area) you only have two measurements. So a carpet 4 ft x 4 ft has a square footage of 16 square feet. And a carpet of 4 ft x 8 ft has a square footage of 32 square feet. Three measurements like 4 ft x 4 ft x 8 ft give you cubic footage, or volume. So the volume of a container that size would be 128 cubic feet.

8 ft X 6 ft = 48 sq.ft. ( NOT ft^(2)).
240 square feet
Area = 12 ft * 8 ft = 96 sq ft.
4' * 8' = 4*8 sq ft = 32 sq ft
Area of the circle: pi*8^2 = 201 square feet rounded
Assuming the room is 8 ft by 10 ft (the question does not say so), the area would be 8*10 = 80 square feet
1'4 * 8' = 11/3' * 8' = 102/3 sq ft.
Since you know the length you know the linear footage. Next: measure the width and multiply the width by the length, this will give you the area or sq. footage. Length x width. For example: a room 8 ft. long x 10 ft. wide would be 64 square feet. The length is important because your carpet at the big box store is 10 feet wide and you only need 8 linear feet. In this case the square footage is: 8 ft. x 10 ft. = 80 sq. feet.
It is 12 x 8 = 96 sq. ft.
