The equation V equals pi r squared h, where r represents radius and h represents height, is used to find the volume of a _______

baherus [9]

Answer:

Volume of a cylinder.

Step-by-step explanation:

The given equation is :

$V=\pi r^2 h$

Where

r is the radius

h is the height

This equation is used to find the volume of a cylinder.

For example, a cylinder having radius of 7 units and height of 10 units, its volume will be :

$V=\dfrac{22}{7}\times 7^2\times 10\\\\V=1540\ \text{unit}^2$

So, the given equation is used to find the volume of a cylinder.

Please help! Thanks!: If a 95% confidence interval was being calculated using the following expression:

Roman55 [17]

The confidence interval can be calculated from the margin of error, and vice versa,

The margin of error of the confidence interval is 2.156

The confidence interval is given as:

$\mathbf{CI = 3.2 \pm 1.96 \cdot 1.1}$

The formula of confidence interval is:

$\mathbf{CI = \bar x\pm E}$

Where E represents the margin of error.

So, by comparison:

$\mathbf{E = 1.96 \cdot 1.1}$

Multiply

$\mathbf{E = 2.156}$

Hence, the margin of error of the confidence interval is 2.156
