∙ 8y agoAssuming 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 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
A foot is a unit of length, while a square foot is a unit of area. A square foot is the area of a square with sides that are each one foot in length. So, one square foot is equal to 1 foot times 1 foot, or 1 square foot is equal to 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
Area of any circle = (pi) x (radius)2Radius = 1/2 diameterArea of this circle = (pi) x (2 ft)2 = 4 pi square feet = 12.566 square feet (rounded)
