Answer:

 \large \underline{ \sf{ \pmb{Given}}}

  • ~Radius of Cylinder = 7 cm
  • ~Height of Cylinder = 6 cm

 \large \underline {\sf {\pmb{To \:  Find }}}

  • ~Curved surface area of cylinder

  \large \underline {\sf \pmb{Using \: Formula}}

 \circ\underline{ \boxed {\sf{Area of  \: the \: curved \:  surface = 2 {\pi}rh}}}

 \large\underline{ \sf \pmb {Solution}}

{ \implies\sf{Area of  \: the \: curved \:  surface = 2 {\pi}rh}}

  •   \underline\frak{\pmb{Substituting  \: the  \: values }}

{ :  \implies\sf{Area of  \: the \: curved \:  surface = 2 \times  { \dfrac{22}{7} } \times 7 \times6 }}

{  : \implies\sf{Area of  \: the \: curved \:  surface = 2 \times  { \dfrac{22} {\cancel{7} }} \times  \cancel{7}\times6 }}

{  : \implies\sf{Area of  \: the \: curved \:  surface = 2 \times 22\times6 }}

{ :  \implies\bf \red{Area of  \: the \: curved \:  surface =  264 \: {cm}^{2}  }}

\large \star{\underline{\boxed{\frak{ \pmb {\purple{Area of  \: the \: curved \:  surface =  264 \: {cm}^{2}  }}}}}}

✠ Cylinder

➣ A cylinder has two flat ends in the shape of circles. These two faces are connected by a curved face that looks like a tube. If you make a flat net for a cylinder, it looks like a rectangle with a circle attached at each end.

  • \bf\red{Cylinder} - A cylinder is a shape with two circular ends connected by a curved face.
  • \bf\red{Face} - A cylinder has three faces. Two are flat circles and the third is curved into a tube.
  • \bf\red{Edge} - An edge is the line where two faces meet. Cylinders have two edges that run around the two circular ends and connect with the curved face.
  • \bf\red{Net} - The net of a cylinder is formed of two circles, with one attached to each end of a rectangle.
  • \bf\red{Circle} - The two circular ends are flat on the cylinder so look the same in the flat net.
  • ➟ \bf\red{Rectangle} - The tube part of a cylinder looks like a rectangle in the flat net. To make the cylinder, it has to be curved around to follow the edges of the circular ends.
