Answer 1

Answer: 1252.02 gm

Step-by-step explanation:

Diameter of inner circle = 9 cm

radius =9/2 = 4.5 cm

Diameter of outer circle = 10 cm

radius =10/2= 5 cm

volume of sphere =

4/3× 22/7× (r1^3 - r2^3)

where r1 and r2 are radius.

Using this ,

volume = 4/3×22/7× (5^3-4.5^3)

volume = 4/3×22/7× 33.875

= 141.95238 cm^3

1 cm^3 has mass of 8.82 gm

141.95238 cm^3 will have mass of = =8.82×141.95238

= 1252.02 grams.
