The diameter of a A. 1428 cm3
B. 1439 cm3
C. 
D. 1440 cm3
Answer :
Given: Diameter of the sphere is 14cm
Radius of the sphere is 
= 7cm
Volume of the Sphere is given by: 
πr3 (here r is the radius of the sphere)
Let V be the volume of the sphere)
∴ V = 
πr3
⇒ V = 
π(7)3 = 
× 343
⇒ V = 
× 22 × 49 = 
= 1437
∴ Volume of the sphere is 1437
