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.
Area = pi*r2r(radius) = diameter/2 = 16 feet/2 = 8 feetArea = pi(8 ft)2= 201 ft2======
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.
48
6 * 8 = 48 square ft.
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
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.
1'4 * 8' = 11/3' * 8' = 102/3 sq ft.
It is 12 x 8 = 96 sq. ft.
