Surface area of the sphere: 4*pi*2 squared = 50.265 square inches to 3 decimal places
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 the sphere = 4*pi*92 = 1017.87602 or about 1018 sq cm
Surface area of a sphere in square units = 4*pi*radius^2
Surface area of a sphere = 4*pi*radius2 Surface area = 16*pi = 50.26548246 or 50 square inches.
Surface area of a sphere = 4*pi*radius2 radius = diameter/2
Surface area of a sphere = 4*pi*(diameter/2)^squared
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 the sphere = 4*pi*92 = 1017.87602 or about 1018 sq cm
Surface area of sphere: 4*pi*15^2 = 900*pi square cm
The surface area of a 12-inch diameter sphere is 452.39 square inches.The formula for surface area of a sphere is 4*pi*r2 where r=radius
Surface area of a sphere in square units = 4*pi*radius^2
Surface area of a sphere = 4*pi*radius2 Surface area = 16*pi = 50.26548246 or 50 square inches.
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 sphere: 4*pi*6 squared = 452.389 square meters rounded to 3 decimal places
Surface area = 4*pi*radius2 = 50.265 square feet correct to 3 dp
Surface area = 4*pi*3.42 = 181.458 square units to 3 dp
