Area of circle is just $A = \pi r^2$

3. Astrophysics

Or you can use $A = \frac{ 1 }{ 4 }\pi d^2 \implies \frac{ 1 }{ 4 } \pi (6 \sqrt{2})^2$

4. Astrophysics

So $(6\sqrt{2})^2 = (6\sqrt{2})(6\sqrt{2}) = 36 \times 2 = 72$

5. Astrophysics

Finish it off

I'm having a hard time with it. What would be my next step because. I tried multiplying by pi but I get too large of an answer. The answer is suppose to be 56.55

7. Astrophysics

$A = \frac{ 72 }{ 4 } \times \pi$

8. Astrophysics

I was just showing you how to simplify the $(6\sqrt{2})^2$ earlier as above, you just had to plug the value back into the formula.
