## anonymous one year ago find the area of the circle the radius is 3cm

1. Astrophysics

$A = \pi r^2$

2. anonymous

So basically u use what @Astrophysics stated. plug in 3 for r, where r is the radius.

3. anonymous

That is basically it.

$A=3.14*3^{2}$$A=28.26$28.26 is your answer. Can you give me a medal, please?

or we can just leave it as $A=9 \pi$ means the same thing. It's till 28.2...actually I got 28.27 but it's close.
