Given that Y = K sin(x/70), Volume = 200,000, Height of X = 35mm with its base at x = 0.
Find the value of K.
Any help is appreciated, not sure on what equation to input this, my suggestion would be V = Integral(Pi*Y^2)

if the volume is generated by rotating the curve about the x-axis then yes you integrate πk[(sin(x/70)]^2dx using the limits of integration you specify
then equate this to 200000 and find k .It is easy.
