Answer:
Step-by-step explanation:
Volume =
4 × π × r³ / 3 <----- This is our volume equation
= 4 × π × 1.9³ / 3 (Substituted the unknown r for the radius given, 1.9 cm)
= 4 × π × 6.859 / 3 (Cubed it, aka: Multiplied 1.9 by itself thrice, 1.9 × 1.9 × 1.9
= 4 × 21.548184011 / 3 (Multiplied 6.859 by pi "π")
= 86.1927360439 / 3 (Multiplied that by 4)
= 28.7309120146 cm³ (Divided it by 3, gave it a ³ dimension because it is 3D, volume.
≈
28.73cm³ or 28.7cm³ or 29cm³. (rounded answers, hundreths, tenths and ones)
