Answer:

The circumference of the lamp shade is 57 inches.

Explanation:

Given : A lamp shade has a radius of 9 inches.

To find : The circumference of the top of the shade

Solution : A lamp shade is in a sphere form,

So, formula to find the circumference of sphere is

$C=2\pi r$

Now, the radius of lamp is 9 inches and
$\pi=3.14$

Substitute the value in the formula we get,

$C=2\pi r$

C=2* 3.14 * 9

C=56.52

Round to nearest whole number circumference is 57 .

Therefore,The circumference of the lamp shade is 57 inches.
