Surface area of sphere is : A= 4*pie*r^2
The formula for the surface area of a sphere is 4*pi*r2
There is NO equation for the area of a sphere Assuming you mean surface area, the surface area of a sphere of radius r is 4πr^2.
The surface area of a sphere with radius 6 is: 452 square units.
Take the surface area of the sphere as of it was whole, and divide by the amount of the sphere that is missing.
Surface area of a sphere: A = 4πr2So, surface area = 4pi52
Ozone is not a thin shield / shell, but a distributed volume of gas spread out through the entire atmosphere, with a peak value in the lower stratosphere. The question makes no sense, since some ozone is found throughout the atmosphere, and the "ozone layer" is ozone above some threshold concentration, its altitude limits are a function of latitude, and periodically the poles develop a hole. So imagine any answer you like, from less than the "surface area" of the Earth (winter at the South pole), to very slightly more than the "surface area" of the Earth (the entire rest of the year). How about 42?
The surface area of a sphere with a radius of 7cm is about 615.8cm2
This sphere's surface area is 201.06 mm2
Surface area of a sphere = 4*pi*radius2
Surface area of a sphere = 4*pi*radius2
The sphere's surface area is ~1,017.9 square units.
