\huge{\mathbb{\purple{\underline{\orange{GIVEN:-}}}}}

  • Base of cylinder = 2.8 cm
  • Height of cylinder = 5cm

\huge{\mathbb{\red{\underline{\green{TO\:FIND:-}}}}}

  • Surface area of cylinder

\huge{\mathbb{\blue{\underline{\pink{SOLUTION:-}}}}}

Diameter of cylinder = 2.8cm

Radius of cylinder = \dfrac{D}{2}= \dfrac{2.8}{2} = 1.4cm

Height of cylinder = 5cm

\large{\boxed{\color{aqua}{T.S.A.\:of\:cylinder\:=\:2πr(h+r)}}}

Substituting the value in the above formula, we get

\mapsto{\bold{T.S.A.\:=\:2× \frac{22}{7} × 1.4(5+1.4)}}

\mapsto{\bold{T.S.A.\:=\:2×22×0.2×6.4}}
