Answer 2

Let rr cm be the radius of the sphere.

Now, we know that;

Surface area of sphere = 4 π r²

⇒ 4 × \frac{22}{7}

7

22

× r² = 154

⇒ r² = \frac{154 \times 7}{4 \times 22}

4×22

154×7

⇒ r² = 12. 25

⇒ r = √12.25

⇒ r = 3.5 cm.

Now,

Volume of sphere = \frac{4}{3}

π r³

⇒ \frac{4}{3} \times \frac{22}{7} \times \frac{35}{10} \times \frac{35}{10}
