Answer :

**Concept Used:**

The volume of Sphere

The surface area of a sphere = 4πr^{2}

Where r is the radius of the sphere.

**Given:** Surface Area of Sphere = 154 cm^{2}

**Assumption:** Let r be the radius of the sphere.

**Explanation:**

Let us find the radius of sphere first,

The surface area of a sphere = 4πr^{2}

⇒ 154 cm^{2} = 4πr^{2}

Hence, The radius of the sphere = 3.5 cm.

Now, The Volume of the sphere

Putting the value of r in the formula we get,

The volume of the Sphere

**Hence, the volume of the sphere is**
