Answer:
a = 9/c
Step-by-step explanation:
We want to isolate a. To do this, divide both sides of the given equation by c:
9 ca
---- = -----
c c
This yields
a = 9/c
Since they are complementary
x + y = 90
Sin(o) = Cos (90-0)
Therefore, Cos x = Sin y = 4/5 [ Because x and y are complementary]
Since it asks you to estimate, you would round the 4.6 up to 5. The estimate volume would be 125 inches^3; answer C.
The answer is it’s 5 pie over 4
