To find the volume of a cone, we can use the formula V = (
)h/3
We can use 3.14 for pi. So substitute the numbers and set up the equation.
V = (3.14 × 9²)15/3
V = (254.34)15/3
Simplify and we get
V = 1271.7
So our answer would be D. 1272.7 in³

Answer:
The machine takes 25 minutes to make 5 chairs. It would take the machine 160 minutes to make 32 chairs.
Step-by-step explanation:
Divide 2 chairs by 10 minutes to find the amount of chairs made per minute.
2/10 = 0.2 chairs per minute
Divide 5 chairs by 0.2 chairs per minute to find how much time it takes to make 5 chairs.
5/0.2 = 25 minutes
It takes the machine 25 minutes to make 5 chairs.
Divide 32 chairs by 0.2 chairs per minute to find how much time it takes to make 32 chairs.
32/0.2 = 160 minutes
It takes the machine 160 minutes to make 32 chairs.
extraneous root is a solution o an equation that seems to be right but when we check it (by substituting it into the original equation) it turns out not to be right

Given:
In triangle XYZ, J, K and L are midpoints of the sides.
JK = 38, XZ = 96, YX = 56.
To find:
KL, YZ and LZ.
Solution:
We have, J, K and L are midpoints of the sides of triangle XYZ.
JK = 38, XZ = 96, YX = 56.
Midsegment theorem: If a line segment between the midpoints of two sides of the triangle, then the length of the segment is half of the third side.
Using midsegment theorem, we get
And,
L is the midpoint of the side YZ. So,
Therefore, the measures of KL, YZ and LZ are 28, 76 and 38 respectively.
