Question

help

Answer 1

It's another circle question~!
For this one you can use the equation for circle area:
\[A=\pi*r ^{2}\]
So, take the radius you're given (12) and square that. Then multiply the result of that by pi (3.14, as the question instructs) and you should have your answer

Answer 2

3.14 x 12

Answer 3

Ok, ill help.

Answer 4

Do you know what the area of a circle is?

Answer 5

no

Answer 6

Ok, if yo don't already know, thr area of a circle is " (A = π r²).

Answer 7

Which, in today's words, would be said as Pi r squared.

Answer 8

What do you think u do now?

Answer 9

Hello?

Answer 10

idk

Answer 11

Ok.. you put the formula i just gave you into action..do you know how?

Answer 12

what do you mean by that

Answer 13

So, you remember the \(A=\pi r^2\) equation I mentioned earlier today? Use that equation,
To find the radius, it is \(r=\dfrac{1}{2}d\)
so you would plug this in, \(r=\dfrac{1}{2}(12)\)
which equals \(6\)
now you plug that into the equation \(A=\pi r^2\)
\(A=(3.14) (6)^2\) \(\rightarrow\) \(A=113.04\)

so \(113.04\) would be your answer.
