$\large \pink{\frak{Question}}$

Two right circular cones of equal curved surface areas have their slant heights in the ratio of 3:5. Find the ratio of their respective radii.

A-5:3
B-5:7
C-8:3
D-3:5​

Answer 1

Answer:

Let slant heights be 3x and 5x Also, πr1.3x=π.r2.5x

=> 5:3

Answer 2

A) 5:3

Solution, The ratio of their radii is 5:3.
