Answer:

5.09 in

Explanation:

We know that the formula to find the circumference of a circle is:

C = 2πr

Here,

C → Circumference → 32 in

r → radius

Let us find the radius of the circle by substituting the given values.


\sf C = 2\pi r\\\\\sf 32 = 2\pi r\\\\Divide\:both\:sides\:by\:2 \pi \:and\:make\:r\:the \:subject\\\\(32)/(2 \pi) =(2 \pi r)/(2 \pi) \\\\\red{5.09 \:in=r}

Answer:

  • 5.1 inches

------------------

Use circumference formula:

  • C = 2πr

Find the radius by rearranging the formula and substituting 32 for C:

  • r = C/(2π)
  • r = 32/(2*3.14)
  • r = 5.10 inches (rounded)
