Question

Help!!!!! please!!!!!

Answer 1

`3217 \: {in}^(2)`

Solution,

Diameter (d)= 32 in

Radius (r)= 32/2= 16 in

Surface area of sphere:

`4\pi {r}^(2) \\ = 4 * \pi * {(16)}^(2) \\ = 4 * \pi * 256 \\ = 1024\pi \\ = 1024 * 3.142 \\ = 3217.108 \: {in}^(2)`

Hope this helps...

Good luck on your assignment...

Answer 2

A

Explanation:

Diameter = 32 in

r = 32/2 = 16 in

Surface area of sphere = 4πr²

= 4 * 3.142 * 16 * 16

= 3217.408

= 3217 in²
