Answer:
26in
Step-by-step explanation:
Volume of a cylinder = πr²h
Given
height h = 14in
Volume = 7433in³
Required
base d = 2r
r is the radius
get the radius r
7433 = 3.14 * 14r²
7433 = 43.96r²
r² = 7433/43.96
r² = 169.08
r = 13.00
Since the base d = 2r
d = 2(13)
d = 26in
Hence the base of the cylinder is 26in
1) substitute 10x in for the equation.

Answer:
EF = 13.1
FD = 35.3
Step-by-step explanation:
The distance between two points on a number line is the positive difference between their coordinates.
EF = F - E = 19 -5.9
EF = 13.1
__
FD = F - D = 19 -(-16.3) = 19 +16.3
FD = 35.3

Answer:
x = 12.75
∠C = 51.75°
Step-by-step explanation:
The two marked angles are complementary, so ...
(5x -12) +(3x) = 90
8x = 102
x = 102/8
x = 12.75
__
C = (5x -12)° = (5(12.75) -12)°
∠C = 51.75°
__
<em>Check</em>
E = 3x = 38.25, then C+E = 51.75 +38.25 = 90 . . . . as it should
