given ;
h (come)= 3cm
d =5cm
r = d/2= 5/2 = 2.5cm
(objects:Hemisphere, Cone and Cylinder)
solution:-
TSA of toy= CSA of cone + TSA of Hemisphere
= πrl + 3πr²
=πr(l+3r)
=22/7×2.5(3×2.5)
=59cm²
--------------------------------
TSA of cylinder=2πr(r+h)
=2×22/7×2.5(2.5+3)
=86.42cm²
--------------------------------
TSA of cylinder-TSA of toy
86.42cm²-59cm²
27.2cm²
