Question

The radius of a circle is 12 cm. Select ALL correct statements.

Answer 1

Answer:

B, D, and E

Explanation:

First, the formula for the area of a circle is $\pi$$r^{2}$

Since pi is equal to 3.14, all we need is the radius squared. Since your radius is 12, $12^{2}$=144. Therefore, your equation for area will be (3.14)(144), answer B.

Second, the formula for the circumference of a circle is $2\pi r$.

So, 2(3.14)(12), answer D.

Edit: Answer E also says the same as above- it just multiples the 2 and the 12 together. Sorry for the initial error!
