Question

The sphere shown has a diameter of 36 inches. Which choice is closest to its surface area? Use 3.14 to approximate pi.

Answer 1

the surface area of this sphere is 4,069.44
you might need to round this answer up

Answer 2

Surface area of the sphere =
`4069.44 in^2`

Explanation:

Given is a sphere which has diameter of 36 inches.

Let us find radius of the sphere.

Radius of the sphere =
`(36)/(2) =18 inches`

Surface area of the sphere =
`4\pi r^2`

Substitute the value of r in the formula to get

`SA = 4(3.14)(18^2)\\`

`=4069.44 in^2`

Surface area of the sphere =
`4069.44 in^2`
