Answer: 25.12 inches

Explanation:

We know that the circumference of a circle is given by -

$C= \pi d$ , where d = diameter of the circle.

Given : The circular base of a desk lamp has a diameter of 8 inches.

Then, the circumference of the lamp base is given by :-

$C= \pi (8)\text{ inches}$

Substitute
$\pi=3.14$ , we get

$\Rightarrow\ C=(3.14) (8)\text{ inches}$

$\Rightarrow\ C=25.12\text{ inches}$

Hence, the lamp bases circumference= 25.12 inches
