Question

2.
Find the radius of a sphere (in cm) whose volume is 12pie cm3
​

Answer 1

Answer:

volume of sphere=4/3πr³

12π=4/3πr³

12*3/4=π/πr³

8=r³

r=3√8

r=2

Answer 2

Answer:

The radius of a sphere is 3 cm.

Step-by-step explanation:

Given that:

Volume of a sphere is 12π cm³.

To Find:

The radius of a sphere.

We know that:

Volume of a sphere = 4πr³/3

Where,

r = Radius of the sphere.

Finding the radius of a sphere:

⟿ 4πr³/3 = 12π

Cancelling π both sides.

⟿ 4r³/3 = 12

⟿ 4r³ = 12 × 3

⟿ 4r³ = 36

⟿ r³ = 36/4

⟿ r³ = 9

⟿ r³ = 3³

Cancelling power both sides.

⟿ r = 3

∴ The radius of a sphere = 3 cm
