Question 275872
<font face="Garamond" size="+2">


The circumference of a circle is given by:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ C\ =\ 2\pi r]


But you know that the circumference is *[tex \Large \frac{4\pi}{3}]


So:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 2\pi r\ =\ \frac{4\pi}{3}]


Solve for *[tex \Large r] then insert the value of *[tex \Large r] into the formula for the area of a circle and divide the result by 2.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{A}{2}\ =\ \frac{\pi r^2}{2}]
