Question

A closed circular cylinder has radius equal to 3 cm and height 11 cm. Find its total surface area. ​

Answer 1

Answer:

Step-by-step explanation:

Given: Radius=3cm,

Height=13cm

Total surface area of cylinder =2πr(h+r)

=2×22/7×3(11+3)

=(44/7)×3×14

=44×3×2

=264 cm²

Answer 2

Given :-

• Radius of the Cylinder = 3cm
• Height of the Cylinder = 11cm

To Find :-

• Total Surface Area of Cylinder

Solution :-

➟ Total Surface Area = 2πr ( h + r )

➟ Total Surface Area = 2 × 22/7 × 3 ( 11 + 3 )

➟ Total Surface Area = 2 × 22/7 × 3 × 14

➟ Total Surface Area = 2 × 22 × 3 × 2

➟ Total Surface Area = 44 × 6

➟ Total Surface Area = 264cm²

________________

So, T.S.A of Cylinder is 264cm²
