The formula for the volume of a cone is:
We know the radius and the volume, so we can solve for the height.
We start by multiplying both sides by 3.
To finish this problem, we divide both sides by 3.14 to get h on its own.
h = 21.97, so the height of the cone is 21.97 inches.
Answer:
b
Step-by-step explanation:
Answer: 3x - 6 (in^2)
Step-by-step explanation:
base * height / 2
=
3 ( 2x - 4) / 2 (in^2)
= 3x - 6 (in^2)
The horizontal distance from the base of the skyscraper out to the ship is 485.2 feet.
<h3>What is
trigonometric ratio?</h3>
Trigonometric ratio is used to show the relationship between the sides and angles of right angled triangle.
Let d represent the horizontal distance from the base of the skyscraper out to the ship. Since the angle of depression is 67°, hence:
Angle = 90 - 67 = 23°
Using trig ratio:
tan(23) = d/1143
d = 485.2 feet
The horizontal distance from the base of the skyscraper out to the ship is 485.2 feet.

Answer:
an = -5 + 2( n-1)
Step-by-step explanation:
The formula for an arithmetic sequence is
an = a1+ d ( n-1)
where a1 is the first term and d is the common difference
a1 = -5 since it is the first term in the sequence
d = term 2 minus term1
= -3 - (-5)
= -3+5 = 2
an = -5 + 2( n-1)
