Answer:

The answer is 3418.1 ft rounded to the nearest tenth.

Step-by-step explanation:

The total volume of the cylinder can be defined by the Area of circular base * Perpendicular height.

The area of the circular base can be calculated as

$\pi \times {r}^{2}$

where r is the radius of the circular base, which is 8 ft.

The area of the circular base is

$\pi \times {8}^{2} = 64\pi$

We also know the height of the cylinder is 17 ft.

Hence, the volume of the cylinder is

$64\pi \times 17 = 1088\pi = 3418.0528...$

This will be rounded up to 3418.1 with the nearest tenth

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 $-6$ .

Jayden and Chandra are cleaning the house. It has 12 rooms, and each room is about the same size. When Jayden cleans by himself,

madam [21]

We know that

Jayden cleans 12 rooms in---------------> 6 hours
X rooms-------------------------------------> 4 hours
X=4*12/6--------> 48/6---------> 8 rooms
that means Jayden cleans in 4 hours 8 rooms

Chandra cleans 12 rooms in---------------> 12 hours
X rooms-------------------------------------> 4 hours
X=4*12/12--------> 48/12---------> 4 rooms
that means Chandra cleans in 4 hours 4 rooms

the answer is
Jayden = 8 blankrooms
Chandra = 4 blankrooms
