Answer:

x=[tex]\frac{1}{12}[/tex]

Step-by-step explanation:

1/2x - 5 = 10 - 3/4x

4x/2x - 5 × 4x = 10 × 4x - [tex]\frac{3 x 4x}{4x}[/tex]

2 -5 × 4x = 10 × 4 - 3

2 - 20x = 40x - 3

-20x - 40x = -3 - 2

WHAT IS THE AREA OF THE CURVED SURFACE OF A CYLINDER OF BASE RADIUS 4 CM AND HEIGHT 10 CM

Answers

Answer:

The curved surface area of cylinder is 251.42 cm².

Step-by-step explanation:

Here's the required formula to find the curved surface area of cylinder :

[tex]\star\underline{\boxed{\sf{CSA_{(Cylinder)}} = 2\pi rh}}[/tex]

Csa = Curved surface areaπ = 22/7r = radius h = height

Substituting all the given values in the formula to find the curved surface area of cylinder :

[tex]\implies{\tt{CSA_{(Cylinder)}= 2\pi rh}}[/tex]

[tex]{\implies{\tt{CSA_{(Cylinder)} = 2 \times \dfrac{22}{7} \times 4 \times 10}}}[/tex]

[tex]{\implies{\tt{CSA_{(Cylinder)} = 2 \times \dfrac{22}{7} \times 40}}}[/tex]

[tex]{\implies{\tt{CSA_{(Cylinder)} = \dfrac{2 \times 22 \times 40}{7}}}}[/tex]

[tex]{\implies{\tt{CSA_{(Cylinder)} = \dfrac{44 \times 40}{7}}}}[/tex]

[tex]{\implies{\tt{CSA_{(Cylinder)}= \dfrac{1760}{7}}}}[/tex]

[tex]{\implies{\tt{CSA_{(Cylinder)} \approx 251.42 }}}[/tex]

[tex]{\star{\underline{\boxed{\tt{\red{CSA_{(Cylinder)} \approx 251.42 \: {cm}^{2}}}}}}}[/tex]

Hence, the curved surface area of cylinder is 251.42 cm².
