The formula for the volume of a cylinder is
V = π·r²·h
The formula for the volume of a cone is
V = (1/3)π·r²·h
If the cone has the same radius and height as the cylinder, it has 1/3 the volume of the cylinder.
The cone of interest has a volume of (1/3)·(48 in³) = 16 in³.

Answer:
3 miles
Step-by-step explanation:
you walk 1/5 miles for 1/15 hour, the just do 1/5 time 15 = 15/5 =3
∠BDC=30, so ∠CBD + ∠BCD=180-30=150
ΔDBC is isosceles, so ∠CBD=∠BCD=half of 150=75
∠ABC=∠ABD-∠CBD=155-75=80
ΔABC is isosceles, so ∠ABC=∠ACB=80
∠BAC=180-80-80=20
