A hollow sphere has an outer radius of 6 cm and inner radius of 3 cm.
Outer radius (R) = 6 cm
Inner radius (r) = 3 cm
Formula:
Volume of the hollow sphere
⇒ V = \(4\over3\) × π × (R3 - r3)
Calculation:
⇒\(4\over3\) × π × (63- 33)
⇒\(4\over3 \) × p × (216 - 27)
⇒\(4\over3\) × p × (189)
⇒ 252 p cm3
∴ The volume of the given hollow sphere is 252 p cm3.
Confusion Points (π = p) As per the Official Question paper given in exam.
