Answer 2

Answer:

• CSA of sphere = 1382.10 cm² (Approx)

Step-by-step explanation:

Given:

• Volume of sphere = 4851 cm³

To Find:

• CSA of sphere

Now, first we will calculate radius of sphere,

⇒ Volume of sphere = 4/3 πr³

⇒ 4851 = 4/3 × 22/7 × r³

⇒ 4851 = 88/21 × r³

⇒ 101871 = 88 × r³

⇒ r³ = 101871/88

⇒ r³ = 1157.62

⇒ r = 10.49 cm (Approx)

Now, we will calculate CSA of sphere,

⇒ CSA of sphere = 4πr²

⇒ CSA of sphere = 4 × 3.14 × 10.49 × 10.49

⇒ CSA of sphere = 12.56 × 110.04

⇒ CSA of sphere = 1382.10 cm² (Approx)

Hence, CSA of sphere = 1382.10 cm² (Approx)
