The raduis of a circle is 12 cm. What is the area? (Use approximation)

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.

The area is 452 cm2

Step-by-step explanation:

We use the formula:

Area = π (raduis) 2 = π (12cm) '2 = 452, 39 cm2
