Answer: 25.12 inches
Step-by-step explanation:
We know that the circumference of a circle is given by -
[tex]C= \pi d[/tex] , 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 :-
[tex]C= \pi (8)\text{ inches}[/tex]
Substitute [tex]\pi=3.14[/tex] , we get
[tex]\Rightarrow\ C=(3.14) (8)\text{ inches}[/tex]
[tex]\Rightarrow\ C=25.12\text{ inches}[/tex]
Hence, the lamp bases circumference= 25.12 inches
