Question

find the total surface area of a solid cylinder with radius 13.3 cm and height 10.5 CM respectively​

Answer 1

Solution:

• Radius of Cylinder - 13.3 cm
• Height of Cylinder - 10.5 cm

To Find:

• Total surface area of cylinder ?

Formula Used:

Total surface area = 2πrh + 2πr²

After putting the values,

we get;

= 2 × 22/7 × 13.3 × 10.5 + 2 × 22/7 × 13.3 × 13.3

= 877.8 + 1111.8

= 1989.68 cm²

Hope it will be helpful :)

Answer 2

To Find :

• The Total Surface Area of the Cylinder.

Given :

• Height = 10.5 cm

• Radius = 13.3 cm

• π = 22/7

We Know :

"Total Surface area of a Cylinder"

$\blue{\bf{\underline{\boxed{TSA = 2\pi r(h + r)}}}}$

Where,

• TSA = Total Surface Area of the Cylinder

• r = Radius of the Cylinder

• h = Height of the Cylinder

Solution :-

Using the formula for Total Surface Area of a Cylinder , and by substituting the values in it , we get :

$\begin{gathered}\blue{\sf{TSA = 2\pi r(h + r)}} \\ \\ \\ \implies \sf{TSA = 2 \times \dfrac{22}{7} \times 13.3(10.5 + 13.3)} \\ \\ \\ \implies \sf{TSA = 2 \times \dfrac{22}{7} \times 13.3 \times 23.8} \\ \\ \\ \implies \sf{TSA = 2 \times 22 \times 1.9 \times 23.8} \\ \\ \\ \implies \sf{TSA = 1989.68} \\ \\ \\ \therefore \sf{TSA = 1989.68 cm^{2}}\end{gathered}$

Hence , the Total Surface Area of the Cylinder is 1989.68 cm².
