Answer:
V ≈ 68.63 cm³
Step-by-step explanation:
the volume (V) of a sphere is calculated as
V =
πr³
the volume of a hemisphere is half the volume of a sphere, so
V =
×
πr³ =
πr³ , then
V =
π × 3.2³
=
π × 32.768
≈ 68.63 cm³ ( to 2 dec. places )
B- No; because the product of two irrationals can also be rational
