The area is 6/x+5. I hope this helps!
Answer:
cot . (x- π/2)= - tanx
Step-by-step explanation:
cot . (x- π/2)= - tanx
cot .x - cot π/2= - tanx
cot π/2= 1/tanπ/2
But tan π/2= ∞
cot π/2 = 1/∞= 0
cotx - 0= - tanx
cot x = - tanx
cosx/sinx= - sinx/cosx Putting values of cot and tan
cosx/ sinx ( sinx/cos x) = -sinx/cos x (sinx/cos x )
Multiplying both sides with sinx/cos x
1= - sin²x/cos²x
cos²x= - sin²x as cosx = -sinx
Ok, so what you would have to do is plug in all the variables you have provided into the equation. so you should get the equation:
2 (3.14)(2squared)+2 (3.14)(2)(4) <- you get the 4 from multiplying the radius by 2, which will give you the diameter, but it will also give you the height. So just do the math from there. So by putting it into my calculator, I got 74.72.
The height of it is 8 cm.
