Answer:

The first one is 5.

The second one is 6.25

Step-by-step explanation:

Since the cylinders are similar, you can assume that they are proportional.

The equation would be 9/5 = 4.5/x

Cross multiply and divide, and you get the radius of 2.5.

Circumference: 2*2.5=5 pi

Area: 2.5*2.5=6.25 pi

If cot theta = -2, find the value of cot theta + cot (theta -pi) + cot (theta-2pi)
nika2105 [10]

Given:

\cot \theta = -2

To find:

The value of \cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi).

Solution:

We know that,

\cot (\theta -n\pi)=\cot \theta         ...(i)

Where n is an integer.

We have,

\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)

Using (i), it can be written as

\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)=\cot \theta +\cot \theta +\cot \theta

\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)=3\cot \theta

It is given that \cot \theta = -2.

\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)=3(-2)

\cot \theta +\cot (\theta -\pi)+\cot(\theta -2\pi)=-6

Therefore, the value of the given function expression is -6.
