Surface area = 4*pi*82 = 804.248 square feet rounded to 3 dp
The surface area is 804.25 cm2
By axis if you mean its diameter then surface area: 4*pi*8^2 = 256*pi square units

1024pi units2
The formula for the surface area of a sphere is 4 (pi) r2For a radius of 4, the surface area is4 (3.1416) (4)2 = 4 (3.1416)(16) = about 201.06 square units
The surface area is 804.25 cm2
Surface area of a sphere = 4*pi*radius2 Surface area = 16*pi = 50.26548246 or 50 square inches.
By axis if you mean its diameter then surface area: 4*pi*8^2 = 256*pi square units
Surface area of a sphere = 4*pi*radius squared
The answer is given below.
16
1024pi units2
The total surface area is about 743 units2
The total surface area is 2,111.15 ft2
To find the surface area of a sphere, the formula is: 4pi*r2So plug in numbers: 4pi(4)24pi(16)=64pi
4piR2 = 4pi*16 = 2001
Surface Area of Sphere = 4*pi*r2 = 4*pi*22 = 16*pi
