Question

Q1. The volumes of two spheres are 640 cm3 and 270 cm3. Find the ratio of

their diameters. Plz help cie igcse math

Answer 1

Formula

V=4/3
`\pi`R³ => R = ∛3V/4
`\pi`

With V1 = 640 cm³ and V2=270 m³

`\pi` = 22/7

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

Explanation:

Answer 2

`\boxed{\text{\sf \Large 4:3}}`

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

• 10.692036 : 8.019028

• 4:3
