Question

Hello everyone plz help with this it's urgent. Plzz​

Answer 1

t.s.a of fig =c.s.a of cylinder+c.s.a of cone +c.s.a of hemisphere

height f cylinder=10 cm,,radius of cylinder=5 cm,

radius of cone=5 cm,slant height of cone =5 root 2 cm

radius of hemisphere=5 cm

now u can find the ans by the putting the values in the formula..  

answer is 550 cm (approx)

Answer 2

Answer:

Step-by-step explanation:

Total height=20cm

R of cone = R of hemisphere=R of cylinder =5 cm

Height of cone =5 cm

So,height of cylinder=20-(5+5)=10 cm

So,TSA of toy= CSA of cone +CSA of cylinder + CSA of hemisphere.

TSA=pi×rl+2pi×rh+2pi×r^2.........(1)

Now,l^2=r^2+h^2

L^2=5^2+5^2

L^2=25+25=50

L=5 ×root 2

L=5×1.41

L=7.07cm

Now,put it in the (1)

=pi×r(l+2h+2r)

=3.14×5(7.07+2×10+2×5)

=15.7(37.07)

=581.99cm^2

HOPE IT HELPS YOU
