\bf{\underline{\underline \blue{Solution:-}}}

\sf\underline{\red{\:\:\: AnswEr:-\:\:\:}}

The curved surface area of the cylinder = 660 Cm²

\sf\underline{\red{\:\:\: Given:-\:\:\:}}

The height of the cylinder is 21 Cm.

The radius of the cylinder is 5 Cm.

\sf\underline{\red{\:\:\: Need\:To\: Find:-\:\:\:}}

The curved surface area of the cylinder = ?

\bf{\underline{\underline \blue{Explanation:-}}}

\sf\underline{\red{\:\:\: Formula\:Used\: Here:-\:\:\:}}

\bigstar \:  \boxed{ \sf \: C.S.A \:of\:the\: cylinder = 2\pi rh}

\sf\underline{\green{\:\:\: Now,Putting\:the\: values:-\:\:\:}}

\dashrightarrow \sf {Curved \: surface\:area = 2 \times \frac{22}{7} \times 5 \times 21} \\\\

\dashrightarrow \sf {Curved \: surface\:area = 2 \times 22 \times \times 5 \times 3} \\\\

\dashrightarrow \sf {Curved \: surface\:area = 22 \times 30} \\\\

\dashrightarrow \sf {Curved \: surface\:area = 660\:Cm^2} \\\\

\sf\underline{\red{\:\:\: ThereFore:-\:\:\:}}

The curved surface area of the cylinder is 660 Cm².
