Area of a circle = pi*r^2, 2r = diameter

2. anonymous

2*3.14*6

3. anonymous

ohhh yup ur right

4. anonymous

2pi r

@danny_dumond You posted the formula for the circumference, not the area.

6. anonymous

Cool. I keep forgetting to multiply by 2....thanks guys. C=pi*d Area of a circle=A=pi*r^2

7. anonymous

yes i just realized sorry

8. anonymous

2r = diameter r = (diameter/2) $\pi*(\frac{diameter}{2})^{2} =$

Did you get 113.04?

Yep. If you use 3 as pi you'll get 108.
