1.	The outer and the inner radii of a hollow sphere are 12cm and 10cm. Findits volume
Answer» From this information we have to find the volume Outer radius (R) = 12 cm Inner radius (r)= 10 cm Volume of hollow sphere =(4/3)Π (R³ - r³) =(4/3)(22/7)(12³ - 10³) =(88/21)(1728- 1000) =(88/21)(728) =(64064/21) =3050.67cm³

The outer and the inner radii of a hollow sphere are 12cm and 10cm. Findits volume

Answer»

From this information we have to find the volume

Outer radius (R) = 12 cm

Inner radius (r)= 10 cm

Volume of hollow sphere =(4/3)Π (R³ - r³)

=(4/3)(22/7)(12³ - 10³)

=(88/21)(1728- 1000)

=(88/21)(728)

=(64064/21)

=3050.67cm³
