Answer 1

Circle equation:
\(C=2 \pi r\)

plug in r for your answer

Answer 2

3.14

Answer 3

The problem states that the radius of the box is 12 inches. Substitute "r" in the circumference equation for 12 to calculate the answer.

Answer 4

what do i do?

Answer 5

Sure, so the question asks about how much ribbon it takes to go around the outer edge of the box. Since the box is a circle, we can find the length of the ribbon by calculating the circumference.
Like Extrinix explained, the formula for calculating a circle's Circumference is \[C=\pi*r*2\], where C is the circumference, pi is the constant approximately equal to 3.14, and r is the radius of the circle.
Since the problem gives us the radius equal to 12, we just need to use the equation to calculate the circumference.
\[C=\pi*12*2\]
\[C=\pi*24\]
\[C=3.14*24\]
