Q1. The volumes of two spheres are 640 cm3 and 270 cm3. Find the ratio of their diameters. Plz help cie igcse math

Formula

V=4/3R³ => R = ∛3V/4

With V1 = 640 cm³ and V2=270 m³

= 22/7

=> You can substitute the numbers above to calculate R1 and R2

Step-by-step explanation:

Have fun

Step-by-step explanation:

Volume of sphere=4/3πr³

1. 4/3πr³=640

  r=5.346018

  d=10.692036

2. 4/3πr³=270

   r=4.009514

   d=8.019028

Simplify ratio

c is the answer
