Question

Find the lateral surface area of a right circular cylinder, if it has base diameter 6cm and its hights is 12cm.
​

Answer 1

${\huge{\star{\underbrace{\tt{\red{Answer}}}}}}{\huge{\star}}$

Given :

• Base diameter = 6cm
• Height = 12cm

To find :

• Lateral surface area of cylinder.

Solution :

Diameter of base = 6cm

${\sf \therefore \ Radius \ = \ \frac{ \cancel6}{ \cancel2} \ = \ 3cm}$

Now,

${\boxed{\purple{\sf \ \star \ Lateral \: surface \: area \: = 2\pi rh}}}$

here,

• r is radius
• h is height

${\sf{\implies \ Lateral \: surface \: area \: = 2 \times \frac{22}{7} \times 3 \times 12}}$

${\sf{\implies \ Lateral \: surface \: area \: \: = 226.28cm}}$

Hence the lateral surface area of cylinder is 226.28cm

More information

• Volume of cylinder = 2πr²h
• Total surface area of cylinder = 2πr(h+r)

Answer 2

Answer:

Given :

Base diameter = 6cm

Height = 12cm

To find :

Lateral surface area of cylinder.

Solution :

Diameter of base = 6cm

{\sf \therefore \ Radius \ = \ \frac{ \cancel6}{ \cancel2} \ = \ 3cm}∴ Radius =

2

6

= 3cm

Now,

{\boxed{\purple{\sf \ \star \ Lateral \: surface \: area \: = 2\pi rh}}}

⋆ Lateralsurfacearea=2πrh

here,

r is radius

h is height

{\sf{\implies \ Lateral \: surface \: area \: = 2 \times \frac{22}{7} \times 3 \times 12}}⟹ Lateralsurfacearea=2×

×3×12

{\sf{\implies \ Lateral \: surface \: area \: \: = 226.28cm}}⟹ Lateralsurfacearea=226.28cm

Hence the lateral surface area of cylinder is 226.28cm

Volume of cylinder = 2πr²h

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