Answer 2

Answer:

$\red { Height \: of \: the \: cone} \green {= 8\:cm }$

Step-by-step explanation:

$Radius \: of \: base \: of \: a \:cone (r) = 6\:cm$

$Let \: slant \: height = l \:cm$

$Curved \: surface \:Area = 188.4 \:cm^{2}$

$\implies \pi rl = 188.4$

$\implies 3.14 \times 6 \times l = 188.4$

$\implies l = \frac{ 188.4 }{ 3.14 \times 6 }$

$\implies l = 10 \:cm$

$Height \: of \: the \: cone (h) \\= \sqrt{l^{2} - r^{2}}\\= \sqrt{10^{2} - 6^{2}}\\= \sqrt{100 - 36 }\\= \sqrt{64} \\= 8 \:cm$

Therefore.,

$\red { Height \: of \: the \: cone} \green {= 8\:cm }$
