Question

The circumference of a circle is 50.24 centimeters. Find the radius of the circle use 3.14 for pie

Answer 1

r=C over 2pie, so r= 50.24/2(3.14) so its about 8cm 

Answer 2

The equation for circumference is $C=2 \pi r$, so plugging 50.24 in for C and 3.14 in for $\pi$, you get;
$C=2 \pi r\\ 50.24 = 2* (3.14)*r\\ r = \frac{50.24}{6.28}=8$
Thus the radius of the circle is 8.
