Answer:

8π inches or approximately 25.12 inches

Step-by-step explanation:

What's the circumference of a circle?

 ❖ The circumference of a circle is the distance around a circle.

How do we find the circumference of a circle?

 ❖ The formula to find the circumference of a circle is 2πr, where r =    

      radius. We can solve in terms of pi, or approximate pi to 3.14

<u>Solving</u>

  • <u></u>\pi * 4*2
  • \pi *8
  • 8π inches

<u>or</u>

  • <u />3.14*4*2
  • 3.14*8
  • 25.12 inches

Answer:

See below.

Step-by-step explanation:

Hi there!

We are given a circle, and inside that circle, we know that the radius of that circle is 4 inches

We want to find the circumference of the circle.

The circumference (C) is essentially the perimeter of a circle; the formula for the circumference of a circle is 2πr (r is the radius, π is pi)

Since we know the radius, we can substitute that value into the formula

C=2πr, r=4

C=2π*4

C=8π

If you need the answer in terms of pi, then the answer is 8π inches. However, if you need a number, then substitute an approximation for π, which will usually be 3.14 or 22/7

Using 3.14 for example,

C=8*3.14=25.12 inches

Using 22/7 meanwhile,

C=8*22/7=25.14 inches  (rounded to the nearest hundredth)

So the answer is either 8π inches, 25.12 inches, or 25.14 inches (depending on how you need it approximated)

Either way, hope this helps!
