What is the arc length of arc CD in the circle below? Circle A is shown with a radius labeled 15 feet and a central angle marked 45 degrees.
2 answers:
It would be 11.78 or 11.8 rounded
The circumference of a circle is found using the formula:
,
where R is the radius of the circle. So the circumference of our circle is
(ft).
The ratio of the arc length to the circumference is equal to the measure of the central angle to the complete angle. That is:
.
.
Answer: 11.8 (ft)

Answer:
93
Step-by-step explanation:
89+2²
square 2 first
89+4
then add 4
93
Step-by-step explanation:
y isn't directly proportional with x because the graph doesn't cross O the origin, it starts from a y-intercept wich is not a property for proportional portions
The overall answer would be 10 remainder 1
Either one of those angles can be 90 degrees if ABC is a right triangle.
