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>.

Step-by-step explanation:
8qх + 21ру + брx + 28qy
8qх + 28qy + брx + 21ру rearranged the terms to help factoring
4q(2x + 7y) + 3p(2x + 7y)
(2x + 7y)(4q + 3p) or (4q + 3p)(2x + 7y)
