Answer:
72π (in terms of pi)
Step-by-step explanation:
V = π·r²·h
Plug in the values.
V = π·3²·8
Solve.
V = 72π
To leave an equation in terms of pi, just square, multiply, and leave pi at the end.
3² = 9·8 = 72
72π
If you need the answer fully simplified, it is 226.19 (rounded up).

Answer:
∠BDC = 66°
Step-by-step explanation:
∠OCB ≅ ∠OBC, so is 24°. ΔDBC is inscribed in a semicircle, so ∠DBC is a right angle. That makes ∠BDC complementary to ∠BCD:
∠BDC = 90° -24°
∠BDC = 66°
