❤QUESTION :-

Find the total surface area of a cylinder whose radius is 4cm and height is 28cm.

❤ANSWER:-

Radius of the cylinder : 4 cm

Height of the cylinder : 28 cm

Total surface area of a cylinder : 2πr(r+h)​​​

On substituting the values ,

$\implies\bf{2 x 3.14 x 4(4+28) = 803.34 cm^2}$

Answer 2

Given:-

• The cylinder's radius is 4cm and height is 28cm.

To Find:-

• Find the total surface area of a cylinder.

Concept:-

• Firstly let's understand the concept used here.Concept used is Total Surface Area of a cylinder.Substitute the given values in the equation and solve it.

Formulae Applied:-

• TSA of a cylinder = 2πr(r + h)

Solution:-

Radius = 4cm

Height = 28cm

TSA = ??

⟹TSA of a cylinder = 2πr(r + h)

According to the Question we have,

⟹ 2 × 22/7 × 4(4 + 28)

⟹ 44/7 × 4(32)

⟹ 25.14 × 32

⟹ 804.48

⟹ 804.48cm^2

Therefore,

⟹ The Total Surface Area of the cylinder is 804.48cm^2.
