Answer 2

Answer:

$slant \: heigh \: l = 21$

Step-by-step explanation:

given that total surface area of cone = 1540

radius =14

i.e.

$\pi \: r(l + r) = 1540$

$\frac{22}{7} \times 14(l + 14) = 1540$

$l + 14 = 1540 \times \frac{7}{22} \times \frac{1}{14}$

$l + 14 = 35$

$l = 35 - 14$

$l = 21$

slant height

$l = 21$
