Answer:
angle LMN = 67.44°
Area of ΔMNL = 16.66 square units
Step-by-step explanation:
By applying Sine rule in the ΔLMN,
SinM =
SinM = 0.9235
M =
angle = 67.44°
angle of triangle = 180°
67.44 + 38 + angle = 180°
angle = 180 - 105.44
angle= 74.56°
Area of ΔMNL =
= 16.65636093
= 16.66 square units

The formula for the volume, V of a cone is V = (1/3)*π*(radius)^2 * height.
So, as you see you have two variables, radius and height, which means that there are different combinations of radius and height that lead to the same volume.
That implies that your questions is missing some information.
I searched for it and found that the question has a list of answer choices. This is the list:
a) radius 6 inches, height 3 inches
b) diameter 6 inches, height 3 inches
c) diameter 4 inches, height 6 inches
d) diameter 6 inches, height 6 inches
Now you can probe those options to see which leads to an approximate volume of 28 cubic inches.
a) radius 6 in, height 3 in
=> V = (1/3)*3.14*(6in)^2 * 3in = 113.04 in^3 => not possible
b) diameter 6 in, height 3 incdiameter 6 in => radius 3 in=> V = (1/3)*3.14*(3in)^2 * 3in = 28.26 in^3 => this is the answerThe other options lead to values far from 28 in^3.Answer: diameter 6 inches, height 3 inches.
Answer:
d
Step-by-step explanation:
To eliminate the fractions in the equation multiply all term on both sides by the lowest common multiple of 2 and 3, that is 6
3x + 18 = 4x + 6 ← equation with no fractions
Subtract 4x from both sides
- x + 18 = 6 ( subtract 18 from both sides )
- x = - 12 ( multiply both sides by - 1 )
x = 12 → d
