Step-by-step explanation:
The formula used to find volume of cone is:
Height = 24 inches
Radius = ?
We can find Radius using Pythagoras theorem:
Since radius = diameter / 2
so, radius = 7/2
radius = 3.5
Putting values in the formula:
So,

Let the arc is ABC with angle 324 degree, to find the length of that arc follow the steps;
The circumference of the circle E is :C = 2 r π
C = 2 * 40 π = 80 π cm.
Also 324° / 360° = 0.9m Arc (ABC ) = 0.9 * 80 π = 72 π cm
There is also formula for calculating the measure of an arc:
m Arc = r π α / 180°
m Arc = 40 π * 324 / 180
= 40π * 1.8 = 72 π
Now we have to find the exact length ( π ≈ 3.14 )
m Arc ( ABC ) = 72 * 3.14 = 226.08 cm
The length of the wall is approximately 16.7ft high.
To solve this problem, we would use trigonometric ratios.
The sine angle between any two body is the ratio between the opposite and hypotenuse.
Data given;
- angle = 68 degree
- hypotenuse = 18 foot
- opposite = ?
<h3>Trigonometric Ratio</h3>
From the above calculation, the length of the wall is approximately 16.7ft

1.99p = x
x = total cost
1.99p = 1.99 per pound of grapes.
Question 1)The given parabola is:
First we need to convert this equation to the general form similar to:
So, the given equation will be:
Comparing given equation with the general equation, we can write:
p = 2
h = -12
k= -16
The focus of the parabola with squared x terms lies at (h , k+p)
Using the values, we get the focus point of the given parabola (-16, -10)
Question 2.
The equation of the parabola is:
This means:
p=4
h = -3
k =1
The directrix of the parabola with squared y term has the equation of the form:
x = h - p
Using the values, we get
x= - 3 - 4 = -7
So, the equation of the directrix of the parabola will be x = -7
