Answer 2

$\huge \boxed{ \red{answer}}$

the height of cone is 16 cm .

and diameter of the base is 24 cm .

So the height is ? .

we know that,

${l}^{2} = {h}^{2} + {r}^{2}$

$l ^{2} = {16}^{2} + {24}^{2}$

${l}^{2} = 256 + 576$

$l ^{2} = 832$

${l}^{2} = \sqrt{832}$

${l}^{2} = 28.84(approx)$

curved surface area =

3.14×24×28.84

=> 927.4944

total surface area =

3.14×24(24+28.84)

=>

${800.68 \: cm \: }^{2}$
