Question 1

How many solid spheres of radius 3 cm can be formed by melting a bigger solid sphere of radius 24 cm?

24 सेमी त्रिज्या वाले एक बड़े ठोस गोले को पिघलाकर 3 सेमी त्रिज्या के कितने ठोस गोले बनाए जा सकते हैं?


Options

A

B

C

D


Solution:

Correct Answer:

B


Volume of Sphere = V = 43\frac{4}{3} π\pi R3

43\frac{4}{3} π\pi 243 = x ×\times 43\frac{4}{3} π\pi 33

x = 83 = 512

ठोस गोले का आयतन  = V = 43\frac{4}{3} π\pi R3

43\frac{4}{3} π\pi 243 = x ×\times 43\frac{4}{3} π\pi 33

x = 83 = 512
