Tie = 3
Answer:
The volume of the cone is:
- <u>112.6 cubic inches.</u>
Step-by-step explanation:
You should know that the volume of a straight circular cone is equal to:
- Cone volume = (1/3) PI * r ^ 2 * h
Where:
<em>r = radius.
</em>
<em>h = height.
</em>
Since the radius and diameter are not provided in the exercise but the circumference, the circumference formula should be used and the diameter must be cleared:
- Circumference = PI * Diameter.
When clearing you get:
- Diameter = circumference / PI
By replacing the data you get:
- Diameter = 15 inches / PI
- Diameter = 4.77 inches.
Since the radius is equal to half the diameter, then the diameter is equal to 2,385 inches, now having the value of radius we proceed to replace in the volume formula:
- Cone volume = (1/3) PI * 2.385 in^2 * 18.9 in
- Cone volume = 112.581541 in^3
- <u>Cone volume = 112.6 in^3</u>
I think the question would be, In an auto race which is 25,000 meters, there are ten laps covered. How long is the first lap, and what is the percentage of the lap to the total distance?
So that the calculation will be
25000/ 10 = 2500 m (Length of the first lap)
the percentage of the lap to the total distance
(2500/25000) × 100 = 10 %

Well the formula to find slope is m=
or (if that didnt work) y2-y1/x2-x1
so y2 is -9 and y1 is -3 so -9-(-3) is the same as -9+3 or -6
x2 is 8 x1 is -4 so 8-(-4) or 8+4 which is 12
-6/12 is equal -1/2
So the slope would be -1/2
