Answer 1

1) 942 cm³

2) 3 cm

3) 243π yd³

4) 31064.54 cm³

5) 4.31 × 10¹⁴ ft³

Explanation:

1) π×5²×12 = 942

2) 108pi = π×r²×12

r² = 9

r = 3

3) diameter = 18

radius = 9 yd

Volume = π×9²×3 = 243π yd³

4) diameter = 46.25

radius = 23.125

Volume = π×23.125²×18.5

= 31064.53515625 = 31064.53

5) diameter = 225×2214 = 498150

radius = 249075

Volume = π×249075²×2214

= 431,288,166,770,775

= 4.31 × 10¹⁴
