Curved surface area of a cone = pi r l
Let r be the radii of the two cones
Let l1 and l2 be the slant heights of cone 1 and cone 2 respectively.
fraction numerator Curved space surface space area space of space cone space 1 over denominator Curved space surface space area space of space cone space 2 end fraction equals πrl subscript 1 over πrl subscript 2 equals straight l subscript 1 over straight l subscript 2 equals 5 over 8
