Question

Find the ratio of the curved surface area of two cones, if their diameters of the bases
are equal and slant heights are in the ratio 4: 3.
​

Answer 1

Step-by-step explanation:

csa of cone = pie r l

csa of first come =

$3.14 \times 2 \times 4$

= 25.12

csa of second cone =

3.14 * 1.5 * 3

= 14.13

ratio = 25.12/14.13
