What is the radius of a sphere having volume of 4851cm3? (Use π=22/7)
Answer & explanation
Correct answer: option 2
The volume of sphere = 4851cm3
We know that the volume of the sphere = \(\frac{4}{3}\)πr3
\(\frac{4}{3}\)πr3 = 4851
\(\frac{4}{3}\) × \(\frac{22}{7}\) × r3 = 4851
r3 = 4851 × \(\frac{3}{4}\) × \(\frac{7}{22}\)
r3 = 1157.625
r = 10.5 cm
