Question

10. A cylindrical can has a base with a diameter of 6 cm. Its height measures 5 cm. What is the total surface area of the can?

Answer 1

Answer:

• Total surface area of cylinderal can is 150.8 cm²

Step-by-step explanation:

Given that a cylinderal can has base with a diameter of 6 cm and its height measures 5 cm.

So,

Radius = Diameter/2 = 6/2 = 3 cm

We know that,

• TSA of cylinder = 2πr(h + r)

Substituting required values:

➝ TSA = 2 × 22/7 × 3(5 + 3)

➝ TSA = 44/ 7 × 3 × 8

➝ TSA = 1056/7

➝ TSA = 150.8 cm²

Hence,

• Total surface area of cylinderal can is 150.8 cm²

Answer 2

Answer:

Total surface area of cylindrical can :- 150.72 cm²

Step-by-step explanation:

Given:-

• Base of cylindrical can with diameter :- 6 cm , so radius :- 3 cm
• height of cylinder :- 5 cm

To find :-

• Total surface area of cylindrical can

Solution :-

Formula for Total surface area of cylinder :-

2πr(r + h)

putting the known values ,

= 2 × 3.14 × 3 ( 3+5) cm²

= 18.84 × 8 cm²

= 150.72 cm²
