Answer 1

1. V = πr²t

2r = 44 × 7/22

2r = 14

r = 7

..

V = 22/7 × 7² × 30

V = 4620 cm³

..

2. r² = 2156/(22/7 × 14)

r² = 2156/44

r² = 49

r = 7

d = 14

..

K = 22/7 × 14

K = 44 cm

..

3. t = 693/(22/7 × 3,5²)

t = 693/38,5

t = 18 cm

..

4. 4 × 3,14 × 4² × 9

= 12,56 × 144

= 1808,4 cm³

..

5. 3,14 × 25² × 120

= 1962,5 × 120

= 23550 cm³

= 23,55 liter
