Answer:
For all figures,
r=7 cm
l (slant height)= h (height of cylinder)=4 cm
T.S.A of the figure= C.S.A of Cone+C.S.A of cylinder +C.S.A of hemisphere.
CSA of cone: πrl=(3.14)×(7cm)×(4cm)=87.92 cm2
CSA of cylinder: 2πrh=(2)×(3.14)×(7cm)×(4cm)=175.84 cm2
CSA of hemisphere: 2πr2=(2)×(3.14)×(7cm)2=307.72 cm2
