Question

A hollow sphere of internal and external diameters are 4cm and 8cm. find its volume​

Answer 1

Answer:

If solid of one shape is converted into solid of another shape, then Total volume of the solid to be converted = Total volume of the solid into which the given solid is to be converted. SOLUTION : Given : Internal diameter of hollow sphere(d)= 4 cm. external diameter of hollow sphere (D) = 8 cm

Answer 2

Given :-

Diameter (D1) = 8cm

Diameter (D2) = 4cm

Radius (R1) = 4cm

Radius (R2) = 2cm

Now,

Volume of Sphere = 4/3 π(r1-r2)³

V = 4/3π (4-2)³

V = 4/3π × 8

V = 32/3π cm³ Answer.....
