The length of the parametric curve (call it <em>C </em>) is given by

We have


Now,

so that the arc length integral reduces to

which has an approximate value of 53.4596.
Answer: B) 18° C
Step-by-step explanation:
21+(-3) = 21 - 3
= 18
15 = 10 +5 tha is my answer to <span>Right triangle, hypotenuse =10 short= 5 what does the long leg equal
</span>
18:24 = 3/4
4:70 = 2/35
35:105 = 1/3
22:7 = 22/7
12:165 = 4/55
