The acronym for trigs is SOH CAH TOA
Sine means opposite divided by hypotenuse
So, let us find sine.
The opposie side is 16
The hypotenuse is 17.46
Use your calculator
The answer is ≈ 0.9164
Answer:
<h2>Diameter = 6 cm</h2>
Step-by-step explanation:
The formula of a volume of a sphere:
We have V = 36(3.14) cm³ = V = 36π cm³. Substitute:
<em>divide both sides by π</em>
<em>multiply both sides by 3</em>
<em>divide both sides by 4</em>
![R^3=27\to R=\sqrt[3]{27}\\\\R=3\ cm](https://tex.z-dn.net/?f=R%5E3%3D27%5Cto%20R%3D%5Csqrt%5B3%5D%7B27%7D%5C%5C%5C%5CR%3D3%5C%20cm)
The diameter D = 2R.
Therefore D = 2(3 cm) = 6cm
Simultaneous Equations
3x + y = 4
5x - y = 22
The signs of the matching values aren't the same so we add the rest of the equations.
8x = 26
Divide both sides by 8 to get x = 3.25
Now substitute back into the first equation.
(3 x 3.25) + y = 4
9.75 + y = 4
Subtract 9.75 from both sides
y = -5.75
