Answer:
63 degrees and 27 degrees
Step-by-step explanation:
Complementary angles are when two angles add to 90 degrees.
So, we can check if these pairs add up to 90 degrees.
45 + 95 = 140
38 + 42 = 80
30 + 51 = 81
63 + 27 = 90
The only pair of angles that are complementary is 63 degrees and 27 degrees.

Answer:
553.0 in³
Step-by-step explanation:
(please see attached for reference)
Assuming you are asked to find the volume,
the volume of the cylinder is given by
V = πr²h
where,
π=3.142
r = given as 4 inches
h = given as 11 inches
Substituting these values into the formula,
V = πr²h
V = 3.142 x 4² x 11
= 552.99
= 553.0 in³ (rounded to nearest tenth)
