<h3>Answer:</h3>
3 11/15 cm
<h3>Step-by-step explanation:</h3>AE is the angle bisector of ∠A, so divides the sides of the triangle into a proportion:
... BE:CE = BA:CA = 7:8
Then ...
... BE:BC = 7 : (7+8) = 7:15
ΔDBE ~ ΔABC, so DE = 7/15 × AC
... DE = 7/15 × 8 cm = (56/15) cm
... DE = 3 11/15 cm
Volume of a cylinder is defined as:
v = volume
r = radius
h = height.
V = (r^2)h
In this problem,
v = 1,356.48 in^3
r = 6 in
h = ?
Plug our numbers into the volume formula above.
1,356.48 in^3 = (6^2)h
Divide both sides by (6^2) to isolate variable h
12.0 = h
The height of the cylinder is 12.0 inches
