Question

The volume of two spheres are in the ratio 8:27
Find the ratio of their radii
(A) 2:3 (B) 2:9 (C) 1:3 (D) 4:9​

Answer 1

Answer:

A). 2:3

Explanation:

RATIO OF VOLUMES OF SPHERES ARE THE CUBE OF THIER RADIUS

Answer 2

2:3 is the answer.

Explanation:-

Volume of sphere:- 4/3pie r^3

Let the volumes be 8x^3 and 27x^3

And radius be r1 and r2 respectively

ATQ=>8x^3/27x^3=4/3pie r1^3/4/3pie r2^3

=>8/27 = r1^3/r2^3

:.r1:r2=2:3
