The surface area of a cylinder with circular bases of radius <em>r</em> and height <em>h</em> is equal to the sum of the areas of the two circular faces and the area of the rectangular lateral surface:
<em>A</em> = 2π<em>r</em>² + 2π<em>rh</em>
If you know the height <em>h</em>, then you can solve the quadratic equation for <em>r</em>.
the answer to this question is $250
Ok so direct variation is y=xk
invers is y=k/x
it seems to be that x is on top
therefor
y=x times 1/3
y=xk
direct variation
I’m pretty sure it’s 60 but I’m not 100% sure so I’m sorry if it’s wrong
