Question

6. The cone is standing on the round bottomed Hemisphere bring their flat faced
Together what is the total surface area of this toy.
A) rl + 2112
B) Tr2 h + 2tt r2
C) ir Inr
D) trl + 2 r2​

Answer 1

$Let \: Radius \: of \: the \: base \: of \\a\:cone =r\:units$

$Slant \:height = l \:units$

$Radius \:of \:the \: Hemisphere = r \:units$

/*According to the problem given */

The cone is standing on the round bottomed Hemisphere bring their flat facedTogether

$\red{ Total \: surface \:Area \: of \:the\:Toy}\\= Curved \: surface \:area \:of \:the \:cone \\+ Curved \:surface \:area \:of \:the \: hemisphere\\= \pi rl + 2\pi r^{2} \\= \pi r( l + 2r ) \:square \:units$

Therefore.,

$\red{ Total \: surface \:Area \: of \:the\:Toy}\\\green { = \pi rl + 2\pi r^{2}} \\\green{= \pi r( l + 2r ) \:square \:units}$
