The volume of a _________ is equal to ___ the volume of a cylinder that has the same base and height. The formula for the volume

katrin2010 [14]

Answer:

cone, $\frac{1}{3}$ , $\frac{1}{3} \pi r^{2}h$ , $\pi r^{2}$ , base, h, height, same, $\frac{1}{3}$ , $\frac{1}{3}$ , 3

Step-by-step explanation:

The volume of a cone is equal to $\frac{1}{3}$ the volume of a cylinder that has the same base and height. The formula for the volume of a cone is $\frac{1}{3}\pi r^{2}h$ . stands for the area of the base and h is the height of the cone. Knowing this, we could quickly find the volume of a cone that has the same base and height as a cylinder with a volume of 9 cubic cm. Since the volume of a cone is $\frac{1}{3}$ the volume of a cylinder (with the same base and height), we would multiply 9* $\frac{1}{3}$ to obtain a volume of 3 cubic cm.

one of the Interior angles of a triangle is equal to 30 degrees and one of the exterior angles is equal to 40 degrees find the r

Sonja [21]

If one of the exterior angles is 40, you can find its adjacent interior angle by subtracting 40 from 180. This is 40, so the triangle has 2 interior angles that are equal to 40. Now we have 2 of 3 interior angles. The sum of the measures of the interior angles of a triangle is 180, so we can set this equation up:

x + 40 + 40 = 180
x + 80 = 180
x = 100

So the triangle's angles have measures of 40,40 and 100 degrees.

Suppose we take two different random samples from the same population of test scores. The population mean and standard deviation

Leto [7]

Answer:

The 95% confidence interval obtained with a sample size of 64 will give greater precision.

Step-by-step explanation:

We are given the following in the question:

A 95% confidence interval is calculated with the following sample sizes

$n_1 = 25\\n_2 = 64$

The population mean and standard deviation are unknown.

Effect of sample size on confidence interval:

As the sample size increases the margin of error decreases.
As the margin of error decreases the width of the confidence level decreases.
Thus, with increased sample size the width of confidence level decreases.

If we want a confidence interval with greater precision that is smaller width, we have to choose the higher sample size.

Thus, the 95% confidence interval obtained with a sample size of 64 will give greater precision.
