1) CSA of cone = πrl
Given , l = 10 cm
r = 21 cm
CSA = 22/7 x 21 x 10 = 660 sq cm
2) Volume of sphere = 4/3πr^3
Given, r = 21 cm
Volume = 4/3 x 22/7 x 21 x 21 x 21 = 38808 cubic cm
Hope This Helps You!

3. radius of cone is 21 cm
slant height ,l is 10 cm
CSA of cone =πrl
=22/7×21×10
=660 cm2
4.radius of sphere is 21cm
volume of sphere =4/3πr^3
=4/3×22/7×21×21×21
=38808 cm3
