The formula for calculating the surface area of a sphere is:
A= 4pr2
So your first step is to find what your r is.
r=d/2
=8/2
=4
Now all you have to do is plug your r into the equation.
A= 4p42
= 4p16
= 4*3.14*16
= 200.96in2
Note: p means pi.
: * means multiply
Approximately 50.265 square inches.
Surface area of a sphere = 4*pi*radius2 Surface area = 16*pi = 50.26548246 or 50 square inches.
The surface area is 314.16 inches2
SA = ~314.159 square inches.
The surface of a sphere is calculated pi*d2 or 4 *pi*r2 So if you have a sphere with diameter 8 (units) the area is 804.25 inches squared
The approximate volume of a sphere with a diameter of 8 inches is 268 cubic inches.
Approximately 50.265 square inches.
The approximate surface area of a sphere with a diameter of 15 centimeters is 707cm2
Approximately 50.265 square inches.
The surface area of a sphere with a diameter of 8 inches is 201.1 inches2
The surface area of a sphere with a diameter of 2.7 inches is about 23 square inches.
The surface area of a sphere with a diameter of 25 inches is about 1,963.5 square inches.
The surface area, to the nearest tenth, of a sphere that has a diameter of 14 inches is: 615.8 inches2
The surface area of a sphere with a diameter of 14 inches is about 615.8 square inches.
Surface area of a sphere = 4*pi*radius2 Surface area = 16*pi = 50.26548246 or 50 square inches.
The surface area is 314.16 inches2
SA = ~314.159 square inches.
