Question

Find the surface area of a cylinder whose height is 6 cm and diameter is 2 cm

Answer 1

$\bf \red{ \underline{ \underline{given}}}$

• Height, h=6cm
• Diameter = d/2=>2/2=>radius=1 cm

$\bf \red{ \underline{ \underline{to \: find \: out}}}$

the surface area of a cylinder

$\bf \red{ \underline{ \underline{formula \: used}}}$

$surface \: area = \pink{2\pi \: r(r + h)}$

$\bf \red{ \underline{ \underline{solution}}}$

$surface \: area = 2\pi \: r(r + h)$

$\star \green{\: putting \: the \: value}$

$= > 2 \times \frac{22}{7} \times 1(1 + 6)$

$= > 2 \times \frac{22}{7} \times 7$

$= > 44$

Answer 2

Given:

• Height,h = 6cm

• Diameter = d/2 = 2/2 = Radius = 1cm.

To find out:

The surface area of cylinder.

Formula used:

Surface area = 2πr(r + h)

Solutions:

Surface area = 2πr(r + h)

Putting the value.

2 × 22/7 × 1(1 + 6)

2 × 22/7 × 7

44.
