By definition, the surface area of a sphere is given by:
[tex] A = 4 * \pi * r ^ 2
[/tex]
Where,
r: sphere radius
Substituting values in the given equation we have:
[tex] A = 4 * 3.14 * 8 ^ 2
[/tex]
Doing the calculations we have:
[tex] A = 803.84
[/tex]
Rounding to the nearest tenth:
[tex] A = 803.8 cm ^ 2
[/tex]
Answer:
The surface area of a sphere with a radius of 8cm is:
B. 803.8 cm ^ 2
