Answer:
SA = 201 in^2
Step-by-step explanation:
The formula for surface area of a sphere is
SA = 4pi r^2
We know that the diameter is 8
To find the radius we cut the diameter in half.
r = d/2
r = 8/2 =4
Substitute in what we know.
SA = 4 *pi *4^2
= 4*pi*16
= 64*pi
Letting pi = 3.14
= 200.96 in^2
We want to round to the nearest whole number
SA = 201 in^2
