Question

The radius and slant height of cone is 2 cm and 6 CM respectively its curved surface area is

Answer 1

Given :-

• Radius of cone = 2 cm
• Slant height of cone = 6 cm

To find :-

• Curved Surface Area of cone.

Formula used :-

$\bf \:Curved \: Surface \: Area \: of \: cone \: = \pi \: rl$

where,

• r = radius of cone
• l = slant height of cone

Solution :-

Radius of cone = 2 cm

Slant height of cone = 6 cm

So, Curved Surface Area of cone

$\bf \: = \pi \: rl$

$\bf\implies \: = \dfrac{22}{7} \times 2 \times 6$

$\bf\implies \:\dfrac{264}{7} \: {cm}^{2}$

$\bf\implies \:Curved \: Surface \: Area \: of \: cone = \dfrac{264}{7} \: {cm}^{2}$
