He discovered the relationship between a sphere and a circumscribed cylinder of the same height and diameter. The volume is 4⁄3πr3 for the sphere, and 2πr3 for the cylinder. The surface area is 4πr2 for the sphere, and 6πr2 for the cylinder (including its two bases), where r is the radius of the sphere and cylinder. The sphere has a volume and surface area two-thirds that of the cylinder. A sculpted sphere and cylinder were placed on the tomb of Archimedes at his request.
The volume of a sphere with a diameter of 7 meters is about 179.6m3
Surface area of sphere: 4*pi*6 squared = 452.389 square meters rounded to 3 decimal places
The surface area of a sphere with a diameter of 7cm is 153.9cm2
Surface area of a sphere = 4*pi*radius2 radius = diameter/2

-- You have to ask somebody for the radius of the sphere, in meters. If they tell you the diameter instead, then the radius is 1/2 of the diameter, in meters. -- Multiply (4) times (pi) times (the radius)2 . That's the surface area of the sphere, in square meters. -- Round the answer to the nearest square meter.
Surface area of sphere: 4*pi*6 squared = 452.389 square meters rounded to 3 decimal places
The surface area of a sphere with a diameter of 7cm is 153.9cm2
The surface area of a sphere if its diameter is 9.65 cm equals 292.6cm2
The surface area of a sphere whose diameter is 18cm is 1018cm2
The surface area of a sphere with a diameter of 8 inches is 201.1 inches2
Surface area of a sphere = 4*pi*(diameter/2)^squared
Surface area of a sphere = 4*pi*radius2 radius = diameter/2
A sphere has less surface with the same diameter.
The sphere's diameter is 3.921 cm
