If the volume of a sphere is 972π cm3, then find its radius.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 9 cm
Given:
Volume of a sphere is 972π cm3
Formula used:
Volume of sphere = (4/3)πr3
where r = radius
Calculations:
Using equation (1) we get
Volume of sphere = 972π
⇒ (4/3)πr3 = 972π
⇒ r3 = 729
⇒ r = 9 cm
