What is the area of the circle if the radius is 2 cm?

A. 3 cm squared
B. 6 cm squared
C. 10 cm squared
D. 12 cm squared

I don't really know the answer to this one because I am not sure what the formula for area of a circle is. If I knew the formula the maybe I could figure the answer.

pi r^2

or
pi*r*r (multiply)

if you use 3 for pi then you will get your answer.

diameter gahhhh

the answer is 12 square

To find the area of a circle, you can use the formula A = πr^2, where A represents the area and r represents the radius.

In this case, the given radius is 2 cm. Plugging this value into the formula, we have:

A = π(2 cm)^2
A = π(4 cm^2)
A = 4π cm^2

Now, since the options provided are in the form of integers, you'll need to use an approximation for π. A commonly used approximation is 3.14.

So, substituting π with 3.14, the area of the circle would be:

A ≈ 4(3.14) cm^2
A ≈ 12.56 cm^2

Comparing this result with the given options, the closest one is option D, which states 12 cm squared. However, since the actual value is slightly greater than 12, the correct answer would be:

D. 12 cm squared
