Well, let's first find the area of this circle. Area is \[\pi r^2\]Can you figure this out?

Go ahead and solve it, I'll correct you if you're wrong :) (Remember that r stands for radius)

Sure! Okay, so a radius is half of a diameter, right? |dw:1396374158690:dw| |dw:1396374202544:dw| A diameter is across a circle, radius is half of a circle. So, we need to cut 14 in half. What is 14/2?
