The radius of a circle 6 cm what is the circles area?

dolphi86 [110]

Answer:

113.04 cm

Step-by-step explanation:

We know the formula to find the area of a circle is

$A= pi(r^{2})$

And we are told to use 3.14 instead of pi so what we have now is,

$A=3.14(r^{2})$

We are also told the radius, r, is 6. So our equation now looks like this,

$A=3.14(6^{2})\\\\6^{2}$ is the same as 36, because 6x6 is 36.

Now we have,

$A=3.14(36)$

Which equals 113.04 and that is the area!

Hope that helps and have a great day!
