Question

Curved surface area ( in sq. cm) of cylinder of diameter 14 cm and height 10 cm, is​

Answer 1

Given:-

$\bf\implies Diameter\longrightarrow 14cm$

$\bf\implies Radius \longrightarrow 7cm$

$\bf\implies Height \longrightarrow 10cm$

To Find:-

$\bf\implies C.S.A$

Solution:-

$\bf\implies C.S.A \longrightarrow 2πrh$

$\bf\implies C.S.A \longrightarrow 2×\frac{22}{7}×7×10$

$\bf\implies C.S.A \longrightarrow 2×22×10$

$\bf\implies C.S.A \longrightarrow 440cm²$

$\bf\implies\boxed{C.S.A \longrightarrow 440cm²}$
