What is the surface area of a sphere with a radius of 16 units?

Answer:
D. 1024 π units²
Step-by-step explanation:
We have sphere, with a radius of 16 units.
The surface area of a sphere is given by the following formula:
Surface Area of a sphere = 4 π r²
We already know r, which is 16. So,
SA = 4 * π * 16² = 256 * 4 * π = 1024 π units²
That's enough for our answer, which matches answer D from the list.
If we want to have an actual number.... we would have to multiply 1024 by π.
SA = 1024 * π = 3217 units²
Answer:
option D
1024π units²
Step-by-step explanation:
Given in the question that radius of a sphere = 16 unit
Formula to use to calculate the surface area of the sphere
here r is the radius of the sphere
4 π (16)²
4 π (256)
1024π units²
Surface area of a sphere with radius 16 units = 1024π units²
