Answer 1

Answer:

20231.86cm²

Step-by-step explanation:

A=2πrh+2πr2
2×π×56×1.5+2×π×562=

20231.85669cm²

Answer 2

Answer:

Appropriate Question :-

• Find the curved surface area of the cylinder having the following dimensions : Radius of base = 56 cm and height = 1.5 cm.

Given :-

• A cylinder whose radius of base is 56 cm and height is 1.5 cm.

To Find :-

• What is the curved surface area of the cylinder.

Formula Used :-

$\clubsuit$ Curved Surface Area of Cylinder Formula :

$\small \bigstar \: \: \sf\boxed{\bold{\pink{Curved\: Surface\: Area_{(Cylinder)} =\: 2{\pi}rh}}}\: \: \: \bigstar$

where,

• π = Pie or 22/7
• r = Radius
• h = Height

Solution :-

Given :

• Radius (r) = 56 cm
• Height (h) = 1.5 cm

According to the question by using the formula we get,

$\small \implies \bf Curved\: Surface\: Area_{(Cylinder)} =\: 2{\pi}rh$

$\small \implies \sf Curved\: Surface\: Area_{(Cylinder)} =\: 2 \times \dfrac{22}{7} \times 56 \times 1.5$

$\small \implies \sf Curved\: Surface\: Area_{(Cylinder)} =\: \dfrac{2 \times 22}{7} \times 56 \times 1.5$

$\small \implies \sf Curved\: Surface\: Area_{(Cylinder)} =\: \dfrac{44}{7} \times 84$

$\small \implies \sf Curved\: Surface\: Area_{(Cylinder)} =\: \dfrac{44 \times 84}{7}$

$\small \implies \sf Curved\: Surface\: Area_{(Cylinder)} =\: \dfrac{\cancel{3696}}{\cancel{7}}$

$\small \implies \sf Curved\: Surface Area_{(Cylinder)} =\: \dfrac{528}{1}$

$\small \implies \sf\bold{\red{Curved\: Surface\: Area_{(Cylinder)} =\: 528\: cm^2}}$

$\small \sf\bold{\purple{\underline{\therefore\: The\: curved\: surface\: area\: of\: the\: cylinder\: is\: 528\: cm^2\: .}}}$
