Find the volume of the cylinder. Round your answer to the nearest hundredth of a cubic meter. The radius is 3m and the height is 6m. What is the volume?
Answer:
169.56
Step-by-step explanation:
169.56
If the radius is 3 m and the height is 6 m. Then the volume of the cylinder will be 196.56 cubic meters.
What is the volume of a right circular cylinder?Suppose that the radius of the considered right circular cylinder is 'r' units.
And let its height be 'h' units.
Then, its volume is given as:
V = πr² h
Right circular cylinder is the cylinder in which the line joining the center of the top circle of the cylinder to the center of the base circle of the cylinder is perpendicular to the surface of its base, and to the top.
The radius is 3 m and the height is 6 m.
Then the volume of the cylinder will be
Volume = 3.14 x 3² x 6
Volume = 3.14 x 9 x 6
Volume = 169.56 m³

Step-by-step explanation:
To be considered 18-karat (18K) gold, a piece of jewelry must be made of 75% pure gold. The higher the karats, the more valuable a piece of jewelry. A jewelry designer is purchasing a large quantity of 18K gold from a new supplier. To see if the new supplier is being dishonest about the karat rating in the shipment, the designer melts a random sample of the gold and conducts a hypothesis test with H0: The proportion of metal that is gold is 75%, and Ha: The proportion of metal that is gold is less than 75%. What is a Type I error and its consequence in this context
Answer:
The gold shipment truly is made of 75% gold, but the designer concludes that it is made of less than 75% gold. The designer will reject the shipment of gold and miss out on an honest business relationship with the supplier.
Step-by-step explanation:
Type I error is defined as the rejection of the true null hypothesis. It is also called as the 'false positive' conclusion or 'false positive' findings. The value of alpha or the significance level determines the probability of making the error type I.
In the context, it is given that for a gold piece to be of 18 karat , the piece of jewelry must be made of 75% of pure gold.
The null hypothesis is, H0: The proportion of metal that is gold is 75%
The alternative hypothesis is Ha: The proportion of metal that is gold is less than 75%.
Thus the type I error is when the gold shipment is made of 75% gold but the jewelry designer rejects the shipment thinking that the shipment is made of less than 75% gold.
Thus it shows the error of type I rejecting the null hypothesis.

A hot air balloon went from an elevation of 5,038 feet to an elevation of 3,403 feet in 30 minutes. What was its rate of descent? The rate of the descent was ( ) feet per minute.
Answer:
Step-by-step explanation:
In this case, we have a descent of 2,125 feet (initial height of 5,439 - ending height of 3,314). Since it took 34 minutes for the balloon to descend this distance, we divide the descent by the time (2,125/34). This gives us a rate of 62.5 feet per minute.
That means that the balloon traveled downward 62.5 feet every minute.

Work out an expression for the nth term of the sequence.
The nth term is n+9
Answer:
9n + 2.
Step-by-step explanation:
This is arithmetic with common difference d = 9.
nth term = a1 + d(n - 1) (a1 = 11) 11 + 9n - 9
= 11 + 9(n - 1)
= 9n + 2.

Find the solutions to x2 = 24.
O A. x = +216
O B. x = 16.6
O C. x= 46
O D. x = +62
Answer:
x =±2 sqrt(6)
Step-by-step explanation:
x^2 = 24
Take the square root of each side
sqrt(x^2) = sqrt(24)
x = ±sqrt(4*6)
x =±sqrt(4) sqrt(6)
x =±2 sqrt(6)

One cube has edges n meters long. Another has edges 3n meters long. What is the ratio of the volume of the first cube to the volume of the second cube
Answer:
1:3
Step-by-step explanation:
The second cube is 3x bigger than the first cube, and since all sides of a cube are the same the ratio for the length of the edges will directly transfer over to the ratio of their volumes.
C. 1 : 27
As an example, let's say that n is equal to 1. The volume of the first cube is n*n*n, since n stands for the measurement of each edge. n*n*n=1*1*1=1 cubic meter. Now, onto the second cube. The volume of the second cube is 3n*3n*3n, since 3n stands for the measurement of each edge. 3n*3n*3n=3*3*3 ( since 3n=3*1=3 ) which is equal to 27. The ratio of the volume of the first cube to the volume of the second cube is represented by n : 3n. Substituting the n on both sides for the n in our example, we get a final result and ratio of 1 : 27.

The solution is, Distance between E and F = 8 units
What is distance?The distance between two points is the length of the line joining the two points.
Formula: distance= √(x_2-x_1)²+(y_2-y_1)²
here, we have,
Given:
Coordinate of E = (3,5)
Coordinate of F = (3,-3)
Find:
Distance between E and F
Computation:
Distance = √(x₁-x₂)² + (y₁-y₂)²
Distance between E and F = √(3-3)² + (5+3)²
Distance between E and F = √(8)²
Distance between E and F = 8 units
