The circumference of a circle is 62.8 centimeters. What is the circle's radius?
Kobotan [32]

Hello!

To solve this exercise, we must use the formula below:

\mathrm{C=2\cdot\pi\cdot r}

  • C = 62.8cm
  • π = 3.14
  • r = ?

Knowing these values, let's replace them in the formula to obtain r:

\mathrm{62.8=2\cdot\ 3.14\cdot r}\\\mathrm{62.8=6.28r}\\\mathrm{6.28r=62.8}\\\\\mathrm{r=\dfrac{62.8}{6.28}}\\\\\boxed{\mathrm{r=10}}

So, the radius of this circle is 10cm.

Hope this helps!
