Answer: 113.04 cm²

Step-by-step explanation: To find the area of a circle, start with the the formula for the area of a circle which is shown below.

$A =\pi r^(2)$

Notice that our circle has a radius of 6 cm so we can plug a 6 in for r in our formula. So we have (π) (6 cm)².

Multiplying, (6 cm)² is equal to 6 cm · 6 cm or 36 cm².

So we have 36π cm².

So the area of the circle is 36π cm².

Now, remember that π is approximately equal to 22/7 or 3.14 so we can estimate the area of the circle by plugging in 3.14 forπ.

So we have (36) (3.14) which is equal to 113.04.

So the area of the circle is approximately equal to 113.04 cm².
