14 fluid ounces = 1.75 cups
C=2(3.14)r Where C is the circumference, and r the radius. Here you give the radius, which is 15, so it will be C=2(3.14)(3) C=18.84ft
Answer:
13) B
14) A
Step-by-step explanation:
13) Knowing that the interior angles of a triangle add up to 180, we can see that angle A is 53°. To find length c, we can use either sine or cosine. Let's use sine:
sin 37° = b/c = 15.9/c ---> c = 15.9/sin 37 = 26.4
To solve for side a, use cosine:
cos 37° = a/26.4 ---> a = 26.4cos37 = 21.1
14) Again, knowing that the interior angles of a triangle add up to 180, we know that angle B is 52°. This time,let's use cosine (although you may choose sine if you want):
cos 38° = b/16 ---> b = 16cos38 = 12.6
To find side a, use sine:
sin 38° = a/16 ---> a = 16sin38 = 9.9
