If the slant height and base radius of a right circular cone are 6.5 and 3.5 respectively, the total surface area of the cone is___(Take π=22/7 )
110 cm2
210 cm2
220 cm2
230 cm2
Given l=6.5,r=3.5
Total Surface area of the tomb= π(l+r)=110sq.cm
The ratio of base radius to slant height of a right circular cone is 3:2. Calculate the ratio of total surface area of cone to curved surface area of the cone.(Take π=227). [3 MARKS]
