Question 429585
In circle O, the m angle DOG = 92° and the length of arc DG is 16. Calculate the length of the radius. Use 3.14 for π. How would you find this? Do not tell me the answer but show me how one would accomplish this problem.
-----------------
{{{C = 2pi*r}}} total circumference
{{{Arc = C*(angle/360)}}}
{{{16 = 2*pi*r(92/360)}}}
r =~ 9.964
----------------
Using radians is recommended, as the other tutor did.
It simplifies things, tho they're scary at first.
