The volume of the prop is calculated to be 2,712.96 cubic inches.
<u>Step-by-step explanation:</u>
Step 1:
The prop consists of a cone and a half-sphere on top. We will have to calculate the volumes of the cone and the half-sphere separately and then add them to obtain the total volume.
Step 2:
The volume of a cone is determined by multiplying with π, the square of the radius (r²) and height (h). Here we substitute π as 3.14. The radius is 9 inches and the height is 14 inches.
The volume of the cone : =
= 1,186.92 cubic inches.
Step 3:
The area of a half-sphere is half of a full sphere. The volume of a sphere is given by multiplying with π and the cube of the radius (r³).
Here the radius is 9 inches. We take π as 3.14.
The volume of a full sphere = =
= 3,052.08 cubic inches.
The volume of the half-sphere = = 1,526.04 cubic inches.
Step 4:
The total volume = The volume of the cone + The volume of the half sphere,
The total volume = 1,186.92 + 1,526.04 = 2,712.96 cubic inches.
Answer:
290ft
Step-by-step explanation:
First, add 40 and 50 together to get the side across giving you 90.
Next, take 60 and subtract 25 for the oposite side giving you 25.
Finally, add all sides together to get 290.
Answer:
The perimeter of the polygon = 18 units
The area of the polygon will be square units
Step-by-step explanation:
<u><em>Computing the Perimeter of the Polygon: </em></u>
Considering the polygon with vertices
- W (11,2)
- X (11,8)
- Y (14,8)
- Z (14,2)
As the polygon is drawn in coordinate plane as shown in figure a.
From the attached figure a, we can observe that
- The length of the side
units
- The length of the side
units
- The length of the side
units
- The length of the side
units
So, the perimeter of the polygon can be calculated by taking the sum of the lengths of all sides i.e.
The perimeter of the polygon =
= 3 + 6 + 6 + 3
= 18 units
<u><em>Computing the Area of the Polygon: </em></u>
Area can be calculated by multiplying the length and width of the polygon.
So, the area will be:
Therefore, the area of the polygon will be square units
