Area of a circle with a 4 feet radius = 16*pi square feet
Assuming the diameter is 4 feet, then the radius is half. 4 / 2 = 2 ft.
4 foot square has 4 feet on each side. Area=4*4=16 sq. ft. Perimeter=4+4+4+4=16 ft.
4*16=64 ft.2
4 pie ft. 2
77.5 sq. ft.
4 ft by 4 ft = 4*4 = 16 square feet.
A cylinder that has a radius of 3 ft and height of 4 ft has a surface area of 131.95 square feet.
Assuming the diameter is 4 feet, then the radius is half. 4 / 2 = 2 ft.
4 ft by 8 ft makes 32 sq ft
4 foot square has 4 feet on each side. Area=4*4=16 sq. ft. Perimeter=4+4+4+4=16 ft.
A room measuring 6 ft by 4 foot.
4 ft X 6 ft = 24 square feet.
4*16=64 ft.2
4 pie ft. 2
'square feet' and' feet' are units of two different properties and cannot be compared. A length can be expressed in feet [ft]. An area can be expressed in square feet [ft^2]. For example, a square has 4 edges of length 1 foot. The area of the square = 1 ft * 1 ft = 1 ft^2 or 1 square foot.
The radius of the circle is 4 .5 ft. Where r is the radius and Pi is the mathematical constant: r2*Pi = area of a circle. Therefore the area of your circle must be 7.069 ft2
24 ft * 24 ft * 4 in = 5.437 cubic metres.
