Q2 of 189 Page 500

Find the volume, curved surface area and the total surface area of a cone whose height and slant height are 6 cm and
10 cm respectively. (Take )

Given,


Height (h) = 6cm


Slant height (l) = 10cm


r =



r


r = 8cm


Volume of the cone =



= 401.92cm2


Curved surface area = πrl


Curved surface area =


= 251.2cm2


Total surface area = πr(r + l)




= 452.16 cm2
