Answer: 452.16 cm²
Step-by-step explanation: To find the area of a circle, start with the formula for the area of a circle.
Area = πr²
Notice that the radius of our circle is 12 cm so we can plug a 12 in for the radius in our formula.
Area = (π)(12cm)²
12 cm² is equal to 12 cm × 12 cm or 144 cm².
Area = 144π cm²
So the area of the circle is 144π 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 for π.
So we have (144)(3.14) which is equal to 452.16 cm².
So the area of the circle is approximately equal to 452.16 cm².
