Answer 2

Answer:

1) Volume of sphere (r = 7cm) =》1436.02cm^3

2)Volume of sphere (r = 1.4cm) =》11.488 cm^3

3)Volume of sphere (r = 105cm) =》4846590 cm^3

4)Volume of sphere (r = 49cm) =》492557.146 cm^3

5) Volume of sphere (r = 21cm) =》38772.72 cm^3

Step-by-step explanation:

We know...

Volume of sphere = 4/3 (pi) r^3

1) r = 7 cm

Volume of sphere = 4/3 (pi) r^3

= 4/3 × 3.14 × (7)^3

= 1436.02 cm^3

2) r = 1.4cm

Volume of sphere = 4/3 (pi) r^3

= 4/3 (3.14) (1.4)^3

=11.488 cm^3

3) r = 105cm

Volume of sphere = 4/3 (pi) r^3

= 4/3 (3.14) (105)^3

= 4,846,590 cm^3

4) r = 49 cm

Volume of sphere = 4/3 (pi) r^3

= 4/3 (3.14) (49)^3

= 492,557.146 cm^3

5) r = 21 cm

Volume of sphere = 4/3 (pi) r^3

= 4/3 (3.14) (21)^3

= 38,772.72 cm^3
