Answer:
7.9
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationship of the hypotenuse and the side opposite an angle:
... Sin = Opposite/Hypotenuse
For your geometry, this is ...
... sin(21°) = x/22
Multiplying by 22 gives ...
... x = 22·sin(21°) ≈ 7.9
Answer:3 0/ (1/3 pi 8^2)
Step-by-step explanation:
the formula for vaume is 1/3pi r^2*h=V
to find the hight you revers it you get 30/ (1/3 pi 8^2)
so you get 30/ (1/3*pi*16)
you then get 30/5.3inf pi
the rusulte is 5.6 pi left in terms of pi
I hope that helps
