Step-by-step explanation:
The volume (V) of a cylinder is
V = area of base × height
here area of base = 64π and height = 10, hence
V = 64π × 10 = 640π in³ ← exact value
Answer:
x ≈ 2879.4 m
Step-by-step explanation:
Measure of ∠DAC = 10°
Measure of ∠DAB = 90°
Measure of ∠BAC = 90° - 10° = 80°
By applying cosine rule in ΔABC,
cos(80°) = 
= 
0.17365 = 
x = 
x = 2879.36
x ≈ 2879.4 m
