Surface area of a sphere = 4*pi*radius2 radius = diameter/2
You divide the diameter by 2, to get the radius. Then you use the formula for the surface area of a sphere. Surface area of a sphere = 4*pi*radius^2
Surface area of a sphere in square units = 4*pi*radius^2
Surface area of the sphere: 4*pi*2 squared = 50.265 square inches to 3 decimal places
First divide the diameter by 2 to give the radius and use the formula:- Surface area of a sphere = 4*pi*radius2 measured in square units
Surface area of a sphere = 4*pi*(diameter/2)^squared
Surface area of a sphere = 4*pi*radius2 radius = diameter/2
You divide the diameter by 2, to get the radius. Then you use the formula for the surface area of a sphere. Surface area of a sphere = 4*pi*radius^2
Surface area of sphere: 4*pi*15^2 = 900*pi square cm
Surface area of a sphere in square units = 4*pi*radius^2
Surface area of the sphere: 4*pi*2 squared = 50.265 square inches to 3 decimal places
First divide the diameter by 2 to give the radius and use the formula:- Surface area of a sphere = 4*pi*radius2 measured in square units
By axis if you mean its diameter then surface area: 4*pi*8^2 = 256*pi square units
-- Take 1/2 of the diameter. That's the 'radius' of the sphere. -- 'Square' the radius. (Multiply it by itself.) -- Multiply the result by 4 pi. You now have the surface area of the sphere. P.S.: There really isn't anything else to know about a sphere other than its diameter.
-- 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.
You are correct my friend! Surface Area of a Sphere is indeed = 4(pi)r^2 and that is also equal to Circumference times Diameter!
Surface area of sphere is : A= 4*pie*r^2
