The complementary angle of 12 degrees, is 78 degrees.
Complementary angles are angles that when added together have an end result of 90 degrees. So, to find the answer, simply subtract 12 from 90. Thus making the answer 78 degrees.
I hope this helps!
Answer:
B
Step-by-step explanation:
If you look at the frequency, only 1/3 is odd. so I would pick 45. 100/3 is 33.3333, so yeah pretty close. The answer is B. Please mark brainliest if correct.
V=(4/3)pir^3
SA=4pir^2
so
V=288=(4/3)pir^3
times both sides by 3/4
216=pir^3
divide both sides by pi
216/pi=r^3
cube root both sides
6/(∛pi)=r
sub into other
sa=4pir^2
sa=4pi(6/(∛pi))^2
SA=4pi(36/(∛(pi²)))
SA=144pi/(∛(pi²))
SA=144pi∛pi/pi
SA=144∛pi
SA≈210.901 in²
not sure what option that's supposed to be
Answer:
45%
Step-by-step explanation:
To find the percentage decrease, we need to find the decrease first.
Decrease = 812 - 446.6
= 365.4
