the circumference of a circle is 11pi inches. what is the area, in square inches, of the circle? express in terms of pi.



Answer :

[tex]2 \pi r=circumference of the circle r=5.5 (5.5) x^{2} \pi =area 30.25 \pi =area[/tex]

30.25[tex] \pi [/tex] square inches is the area for the circle
C= pi d
therefore 11= diameter
radius is 1/2 the diameter
radius= 5.5

A= pi r^2
A=30.25 pi
hope this helps
