Surface area of a sphere = (4 pi) (Radius)2
Radius = 1/2 diameter = 36.5-ft
Surface area = (4 pi) x (36.5)2 = 16,741.5 square feet (rounded)
= 1,860.2 square yards (rounded)
The surface area of a sphere with a diameter of 18 feet is: 1,020 square feet.
A cylinder 10 feet in diameter by 75 feet long has a surface area of 2,513.3 square feet.
The surface area is 1,020 square feet.
The curved surface area is 155.19ft2
A cylinder with a diameter of 1 foot and 3 feet high has a surface area of 11 square 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.
The surface area of this cylinder is 2,111.15 square feet.
1356.48 sq mt Another answer in square feet is : The formula for the surface area of a sphere is 4 x pi x radius squared. The radius is half the diameter, or 3 feet. The radius squared is therefore 9 square feet. The surface area is then 4x3.1415x9 square feet or 113.09 square feet.
The surface area of this sphere is 2,827 square feet.
A sphere having a diameter of 9.5 feet has a surface area of 283.53 square feet and a volume of 448.92 cubic feet.
Surface area of a sphere = 4*pi*radius2 The diameter is 17 feet so the radius is half of this i.e. 8.5 feet. 4*pi*8.52 = 907.9202769 square feet.
Its total surface area is 15614 square feet.
