If the angle measure of a circle is 360, then the equation should be:
2×11+9
22+9
31
This the the way to solve this answer
The answer would be 8746 ft :)
Step-by-step explanation:
r=4.2
cicumference of circle =2Πr=2×3.14×4.2=26.3
The sum of the interior angles of a triangle is 180. Add the three measures given and if you get 180 then those can be the interior angles of a triangle.
