Question

find the TSA of a cylinder of radius 5cm and height 16cm​

Answer 1

Answer:

TSA of cylinder is 660 cm^2

Answer 2

Given :

• radius of cylinder = 5cm

• height of cylinder = 16cm

To find :

• Total surface area

Formula used :

• Total surface area = 2 π r ( h + r)

Solution :

To find TSA use the given formula :-

⟹ Total surface area = 2 π r ( h + r)

Now put :-

• radius of cylinder (r) = 5cm

• height of cylinder (h) = 16cm

• π = 22/7

⟹ Total surface area = 2 × 22/7 × 5 ( 16+5)

⟹ Total surface area = 2 × 22/7 × 5 × 21

⟹ Total surface area = 2 × 22 × 5 × 3

⟹ Total surface area = 660 cm²

ANSWER :

660 cm²

Volume of cylinder = πr²h

T.S.A of cylinder = 2πrh + 2πr²

Volume of cone = ⅓ πr²h

C.S.A of cone = πrl

T.S.A of cone = πrl + πr²

Volume of cuboid = l × b × h

C.S.A of cuboid = 2(l + b)h

T.S.A of cuboid = 2(lb + bh + lh)

C.S.A of cube = 4a²

T.S.A of cube = 6a²

Volume of cube = a³

Volume of sphere = 4/3πr³

Surface area of sphere = 4πr²

Volume of hemisphere = ⅔ πr³

C.S.A of hemisphere = 2πr²

T.S.A of hemisphere = 3πr²
