Question

Find the curved surface area of a cylinder whose radius is 7 cm and height is 7 cm.​

Answer 1

Answer:

CSA of cylinder=2πrh

r=7, h=7

2×22/7×7×7

2×22×7

44×7

=308 cm2

Answer 2

$\fbox\blue{A}\fbox\pink{N}\fbox\red{S}\fbox\green{W}\fbox\orange{E}\fbox\purple{R}$

Height of cylinder = 7cm

Radius of cylinder = 7cm

$\large{\boxed{\pink{Curved\:surface\:area\:=\:2πrh}}}$

Where,

• π = $\frac{22}{7}$
• R = Radius
• H = height

Substituting the value in the above formula, we get :-

$\mapsto{\tt{\orange{Curved\:surface\:area\:=\:2 \times \frac{22}{7} \times 7 \times 7}}}$

$\mapsto{\tt{\orange{Curved\:surface\:area\:=\:2 \times 22 \times 7}}}$

$\large{\boxed{\tt{\green{Curved\: surface\:area\:=\:308cm²}}}}$
