Given height of the cylinder, H = 13 cm
Radius of the cylinder, r = 5 cm
Radius of the hemisphere, r = 5 cm
Height of the cone, h = 12 cm
Radius of the cone, r = 5 cm
Slant height of the cone, l = √(h2+r2)
= √(12)2+(5)2)
= √(144+25)
= √169
= 13 cm
Surface area of the toy = curved surface area of cylinder +curved surface area of hemisphere+ curved surface area of cone
= 2rH+2r2+rl
= r(2H+2r+l)
= (22/7)×5(2×13+2×5+13)
= (110/7)×(26+10+13)
= (110/7)×49
= 110×7
= 770 cm2
Hence the surface area of the toy is 770 cm2.
