Question

hat is the surface area of sphere with diameter 23 ft? 529π ft2 184π ft2 46π ft2 2,116π ft2\

Answer 1

The surface area of the sphere is
`529\pi\ ft^(2)`

Explanation:

we know that

The surface area of a sphere is equal to

`SA=4\pi r^(2)`

we have

`r=23/2=11.5\ ft` ----> the radius is half the diameter

substitute

`SA=4\pi (11.5)^(2)`

`SA=529\pi\ ft^(2)`
