The area of a circle is 16pi cm2. What is the circle's circumstance?

gavmur [86]

I think you mean circumference...Area is $A= \pi r^{2}$ . We have the area so we need to use it to solve for the radius which we will then use in the circumference formula. $16 \pi = \pi r^{2}$ . Divide both sides by pi to get $\frac{16 \pi }{ \pi } = r^{2}$ . Of course the simplification of the left side gives us $16= r^{2}$ and r = 4. Now fill that in to the circumference formula, which is $C=2 \pi r$ , to get C $C=2 \pi (4)$ which is a circumference of $8 \pi$
