The answer is 2,713 in³
The volume (V) of the prop is the sum of the volume of cone (V1) and half of the volume of the sphere (V2): V = V1 + 1/2 * V2
Volume of the cone is:
V1 = π r² h / 3
According to the image,
h = 14 in
r = 9 in
and
π = 3.14
V1 = 3.14 * 9² * 14 / 3 = 1,186.92 in³
The volume of the sphere is:
V2 = π r³ * 4/3
According to the image,
r = 9 in
and
π = 3.14
V2 = 3.14 * 9³ * 4/3 = 3,052.08 in³
The volume of the prop is:
V = V1 + 1/2 * V2
V = 1,186.92 in³ + 1/2 * 3,052.08 in³
V = 1,186.92 in³ + 1,526.04 in³
V = 2,712.96 in³ ≈ 2,713 in³
Answer:
<em>$2,000</em>
<em></em>
Step-by-step explanation:
Let the amount of money they want to raise be $20,000.
We are going to look for 10% of $20000 as shown:
10% of 20,000 = 10/100 * 20,000
= 0.1 * 20,000
= 2,000
<em>Hence the 10% of the money they want to raise is $2,000</em>
<em></em>
<em>Note the the money the amount of money they want to raise was assumed.</em>
Well she probably has 0 blue hair ties and 5 red hair ties.
9. In two years it would be (2,20) find the point on the grid and mark the spot.
In three years it would be (3,40) also mark that spot on the grid.
In four years it would be (4,80) mark this point on the grid
All I'm doing is finding the number of the year and going up till it meets the red line or population amount.
Hope this helped you a little.
The surface area of the square prism is 115 square inches
<h3>surface area of a pyramid</h3>
The surface area of a pyramid is equivalent to the sum of the faces of the pyramid
For the given square pyramid;
TSA = (5*5) + 4(1/2 * 9 * 5)
Simplify to have;
Surface area =25 + 4(45/2)
Surface area = 25 + 180/2
Surface area = 25. + 90
Surface area = 115 square inches
Hence the surface area of the square prism is 115 square inches
