Question

A toy is in the form of a cone mounted on a hemisphere .the diameter of the base and the height oA toy is in the form of a cone mounted on a hemisphere .the diameter of the base and the height of the cone are 6cm and 4cm find the surface areaf the cone are 6cm and 4cm find the surface area

Answer 1

CSA of cone = πrl 
=(22/7)(7)(√(r²+h²))
=(22)(√7²+(31-7)²)
=(22)(√49+576)
=(22)(√625)
=(22)(25)
=550 cm²
CSA of hemisphere=2πr²
=2(22/7)(7²)
=(44/7)(49)
=(44)(7)
=308 cm²
Therefore, total surface area of the toy = CSA of cone + CSA of hemisphere
=550+308
=858 cm²

Answer 2

HLO MATE HERE IS UR ANSWER

A toy in the form of cone mounted on a hemisphere

The diametere of the base = 6 cm

2r = 6

r = 6\ 2

r = 3 { Radius of the base }

and the height of the cone ( h) = 4 cm

WE KNOW THAT

lsquare = h square + r square

= 4 square + 3 square

16 +9

l square = 25

l = root 25

slant height of cone l = root 5

T S A of the toy = C S A of cone and C S A of hemisphere

pie rl + 2 pie r square

pie r ( l + 2 r )

3.14 × 3 ( 5 + {2× 3 } )

9.42 × [ 5+6 ]

9.42 × 11

103.62 cm square

HOPE THIS WILL HELPU
