Question

consider a sphere whose volume is 113 cubic units what will be the radius of the mirror

​

Answer 1

Answer:

Radius of Sphere = 2.99 units

Explanation:

Given : Volume of sphere = 113 cubic units

To find : Radius of sphere

Solution :

Volume of Sphere = 4/3 π r³

Therefore, putting value of volume of sphere in the above equation -

 113 = 4/3 (3.14) r³

 339 = 4 (3.14) r³

 339/4 = 3.14 r³

 84.75 = 3.14 r³

 84.75/3.14 = r³

 26.99 = r³

 r = ∛26.99

 r = 2.99

Answer 2

Given:

The volume of the sphere = 113 cubic units.

To Find:

The radius of the sphere.

Solution:

We know that,

The volume of the sphere = 4/3 π r³.

Since we already know the volume,

113 = 4/3 π r³

r³ = (113 × 3) / 4π.

r³ = 339 / 4π.

r³ = 266.99.

r = 2.99.

Hence, the radius of the sphere is 2.99 units.
