Question:

A solid sphere of radius 4 cm is carved into 27 smaller identical spheres. What is the radius of each smaller sphere?

4 सेमी त्रिज्या वाले एक ठोस गोले को 27 छोटे समान गोलों में उकेरा जाता है। प्रत्येक छोटे गोले की त्रिज्या क्या है?

Options:

  • a) 4/3 cm
  • b) 2/3 cm
  • c) 1/3 cm
  • d) 1/1 cm
  • a) 4/3 सेमी
  • b) 2/3 सेमी
  • c) 1/3 सेमी
  • d) 1/1 सेमी

correct answer : a)

Explanation:

Volume is conserved: (4/3)πR³ = 27 * (4/3)πr³. R³ = 27r³ => r³ = 4³ / 27 => r = 4/3 cm.

आयतन संरक्षित रहता है: (4/3)πR³ = 27 * (4/3)πr³. R³ = 27r³ => r³ = 4³ / 27 => r = 4/3 सेमी।
