The volume of a solid sphere is 4500 π cm3. The surface area of the solid sphere is:
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 900 π cm2.
The volume of a sphere (V) = (4/3)πr3, where r is the radius of the sphere
(4/3)πr3 = 4500π
⇒ r3 = 3375
⇒ r = ³√3375 = 15
The surface area = 4πr2 = 4π(152) = 900π cm2
Therefore, the surface area of the solid sphere is 900π cm2.
