Answer:

curved surface area=440cm^2

total surface area=748 cm^2

volume= 1540 cm^3

Step-by-step explanation:

h = 10cm

r=7cm

NOW,

CSA of cylinder = 2 \pi \: rh

 = 2 \times  \frac{22}{7}  \times 7 \times 10 \\  = 44 \times 10  \\ =   \:  440{cm}^{2}

NOW,

TSA cylinder =

2 \pi \: r(h + r)

 = 2 \times  \frac{22}{7}  \times 7(10 + 7) \\  =  44 \times 17 \\  = 748 {cm}^{2}

NOW,

volume of cylinder =

 \pi  {r}^{2}h

 =  \frac{22}{7}  \times 7  \times 7 \times 10 \\  = 1540{cm}^{3}

Answer :-

  1. Curved surface area of cylinder = 440 cm².
  2. Total surface area of cylinder = 748 cm².
  3. Volume of cylinder = 1540 cm³.

Explanation :-

Height of cylinder = h = 10 cm

Radius of cylinder = r = 7 cm

_______________________[Given]

To find : 1) Curved surface area

2) Total surface area

3) Volume of cylinder

Solution :-

1)Curved surface area of cylinder

= 2πrh

= 2 × (22/7) × 7 × 10

= 44 × 10

= 440 cm²

2)Total surface area of cylinder

= 2πr(h + r)

= 2 × (22/7) × 7(10 + 7)

= 44 × 17

= 748 cm²

3)Volume of cylinder

= πr²h

= (22/7) × (7)² × 10

= 22 × 7 × 10

= 1540 cm³
