Question

Find the surface area of the sphere to the nearest square units (attachment)

Answer 1

The formula for this problem is
\[A=4\pi r^2\]

Now plug in the radius (3) and solve

Answer 2

You would use the formula: A= 4πr2 So you would do 3 squared which is 9 and then you would multiply 9 times 3.14. The number is 28.26. You would then do 28.26 times 4 and you would get 113.04

Answer 3

The nearest square unit is then 113
