If the radius of a sphere is 2.1 cm, then the volume of the sphere is equal to:
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 38.808 cm3.
We know that,
Volume of sphere = 4/3 πr3
here, r = radius = 2.1 cm
Volume = 4/3 × 22/7 × 2.1 × 2.1 × 2.1
⇒ 4/3 × 22/7 × 9.261
⇒ 814.968/21 = 38.808 cm3
