Hello ^_^ Do you know the formula for area of a circle?

toxicwaste · Answer

not really its confusing to me:(

sleepyjess · Answer

That's okay :) The formula is A = $\pi r^2$. So we have the diameter, do you know how to find the radius from the diameter?

toxicwaste · Answer

no but what is

toxicwaste · Answer

pi gamma?

sleepyjess · Answer

To find the radius given the diameter, we just divide the diameter by 2

toxicwaste · Answer

so 201

sleepyjess · Answer

We need to use pi * radius^2

toxicwaste · Answer

The diameter is 16 so the answer would be 201

sleepyjess · Answer

The answer is 201, but do you understand how to get there?
