If the volume of a sphere is 4851 cm3, then what is its diameter (In cm)?
(take π =22/7)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 21
Formula used:
Volume of sphere = 4/3πr3 ---- (1)
Where r is the radius
Calculations:
Using equation (1)
⇒ 4/3 × 22/7 × r3 = 4851
⇒ r3 = 101871/88 = 1157.625
⇒ r = 10.5
Diameter = 2 × radius = 2 × 10.5 = 21
