The radius of a sphere is 4.9 cm. What is the volume of the sphere (approximately)?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 493 cm3.
We know that,
The volume of the sphere = 4/3πr3
Now,
Volume = 4/3 × 22/7 × 4.9 × 4.9 × 4.9
⇒ 4/3 × 22/7 × 117.649
⇒ 4/3 × 22 × 16.807
⇒ 1479.016/3 = 493.00 cm3
