It is the distance from the centre to all points on the surface of a sphere with a radius of 1 foot.
Square footage (surface area) of a 36 inch diameter sphere = 4pir2 pi = 3.1416 r = 1/2 X diameter You asked for square footage; so first convert 36 inches to feet 36 inches / 12 inches/foot = 3 feet r = 1/2 X 3 feet = 1.5 feet surface area = 4 X 3.1416 X (1.5 feet)2 = 28 square feet
The area of a circle whose diameter is 3 feet, is 7.07 sq feet.
Total surface area of a cylinder = (2*p*radius2)+(pi*diameter*height)Total surface area = 1130.973355 or 1131 square feet to the nearest square foot.
There is a problem here. A circle with a 7-foot diameter has a circumference of 21.99 feet, not 10 feet.If the circumference is 10 feet, that would make the diameter 3.183 feet.
A cylinder with a diameter of 1 foot and 3 feet high has a surface area of 11 square feet.
It is the distance from the centre to all points on the surface of a sphere with a radius of 1 foot.
Volume of a sphere = 4/3*pi*radius3 Volume = 4/3*pi*93 = 3053.628059 Volume = 3054 cubic feet to the nearest cubic foot.
No, Sputnik 1, the first spacecraft to orbit earth, was a roughly two foot diameter sphere/ball.
Surface area of a sphere = 4πr²A= 4(3.14159) X 1A= 12.56 ft²

Trinity test, 5 foot diameter sphereHiroshima, 4 foot diameter 10 foot lengthNagasaki, 5 foot diameter 10 foot length
A linear foot is the same as a foot. So, an 18-foot diameter circle would measure 18 linear feet in diameter!
Area of a sphere is 4 pi (radius)2Radius = 1/2 diameterArea of your tank = 4 pi (2)2 = 16 pi = 50.27square feet.(Same area, in principle, inside the tank too.)
