How much paper is required for covering
ice-cream cone completely. The radius is 7 cm
and height is 24​

Answer 1

Answer:

$550 {cm}^{2}$

Step-by-step explanation:

$LSA \: of \: cone \: = \\\pi \: r \: l \\ l = \sqrt{{7}^{2} + {24}^{2} } = \sqrt{49 + 576} = \sqrt{625 }= 25 cm \\ Therefore \: \pi \: r \: l = \frac{22}{7} \times 7 \times 25 \\ = 550 \\ Answer = 550$
