You need to find circumference, so you would multiply the diameter by pi. So your answer is 212pi feet or 666.02 feet
I think it will be set up as 2000(.051)^3
Answer:
-8r
Step-by-step explanation:
r- 9r
since there is an r in each term we can factor out an r
r (1-9)
r (-8)
-8r

it's difficult because you are looking too hard. think simply. why does it tell you that angle is 40°?
Because if you follow the arrow back to where it starts you will see that exact same angle.
so now you know 1 (not m° or n°) angle inside the triangle is 40° and a complete triangle is 180°.
you also know a straight line has 180° on each side. and the line going from m° to n° splits that in half. meaning there is 90° to the right of it and 90° to the left of it. which means n° must equal 90°.
now you know you have 1 angle inside the triangle with 40° and n°=90° now you just need to find how much m° is.
add 40°+90° then Subtract from 180° to get m°.
180°-130°=50°
m°=50°
