So to find a cylinder's volume, you do πr^2*h = volume
So we can fill in a few of the elements.
3.14 * 2.5 ^2 * h = 170
And then we can continue to simplify it.
3.14 * 6.25 * h = 170
19.625 * h = 170
And then to find h,
170/19.625 = about 8.66

Answer: (2α) = cos²(α) - sin²(α)
Step-by-step explanation:
The expression for cosine of the sum of two angles is:
cos (α + β) = cos(α)*cos(β) - sin(α)*sin(β)
in case α = β
cos ( α + α ) = cos (2α) = cos(α)*cos(α) - sin(α)*cos(α)
Hence cos (2α) = cos²(α) - sin²(α)
9.03 divided by 899.8 is closest to a.0.01
I’m not sure what the negative fours are at the end of your problem are for, but the slope of the line passing through those points is 4.
The line itself is y = 4x - 11
