The surphase area of a sphere is S = 4*Pi*r^2 so if r = 16
S = 4*Pi*256 = 1024*Pi

The formula for the surface area of a sphere is
4 X pi X the radius squared
In your case it will be
4 X 22/7 X 16 squared
= 12.5714 X 256
= 3218.2784 square units

surface area = 4pi r^2
4*3.14*16 *16= 3215.36

A=4*pi*r2
A=4*3.1416*(16)^2
A=3216.998 ... almost 3217 units^2

surface area = 4*pi*r^2
so we get 4*pi*16^2
about 3217...

S.A. = 4.Ï.r²
S.A. = 4.Ï.16² units²
S.A. = 3217 units² (to nearest whole number)
