Question

the curved surface area of a right cylinder of height 14 cm is 88 cm². Find the diameter of the base of the cylinder​

Answer 1

Radius = 1 cm

Diameter = 2 × radius

= 2 × 1

= 2 cm

Answer 2

Answer:

$given \: = \\ the \: height \: of \: cylinder \: = 14cm \\ the \: curved \: surface \: area \: of \: cylinder \: = 88cm {}^{2} \\ \: so: \\ the \: curved \: surface \: area \: of \: cylinder \: = 2\pi \: rh \\ and 2r=d</p><p></p><p></p><p>here , r=radius of cylinder , \\  d=diameter of cylinder \\  and h=height of cylinder \\ </p><p></p><p>so , the curved surface area of cylinder =πdh =88cm2</p><p></p><p></p><p>  π×d×14=88</p><p></p><p></p><p> 722×d×14=88</p><p></p><p></p><p>d=2cm</p><p></p><p></p><p> so, the diameter of the cylinder is 2cm.</p><p></p><p>$
