Answer:

The volume of the steel rod is 5,000\ cm^{3}

Step-by-step explanation:

we know that

The volume of the cylinder is equal to

V=Bh

where

B is the area of the base of cylinder

h is the height or length of the cylinder

In this problem we have

B=100\ cm^{2}

h=50\ cm

substitute

V=100*50=5,000\ cm^{3}

A farmer builds a fence to enclose a rectangular pasture.He uses 155 feet of fence. Find the total area of the pasture if it is
ICE Princess25 [194]
The area for the perimeter of a rectangle is:
<em>P = 2l + 2w</em>
In this problem, we are given that P = 155 and l = 45.5. To solve for area, we must find w. To do this, plug in the given info and isolate the w like so:
155=2(45.5)+2w \\ 155=91+2w \\ (155)-91=(91+2w)-91 \\ 64=2w \\  \frac{64}{2} = \frac{2w}{2}  \\ w=32
Now we know w = 32. Knowing all the necessary info, we can use the area formula, <em>A=lw</em>, to solve for A.
A=(45.5)(35) \\ A=1,456

The area is 1,456 sq ft. 

Hope this helps!

Laura has 160 pounds of green beans at her vegetable stand. If she sells 10 pounds of green beans every hour, what is the percen
Mademuasel [1]

Given:

Laura has 160 pounds of green beans at her vegetable stand.

She sells 10 pounds of green beans every hour.

To find:

The percent decrease in green beans after 3 hours.

Solution:

We have,

Beans sold in 1 hour = 10 pounds

So, Beans sold in 3 hours = 30 pounds

Decrease in green beans after 3 hours is 30 pounds.

Now,

\%\text{Decrease}=\dfrac{\text{Decrease in green beans after 3 hours }}{\text{Initial amount of green beans}}\times 100

\%\text{Decrease in green beans after 3 hours}=\dfrac{30}{160}\times 100

\%\text{Decrease in green beans after 3 hours}=\dfrac{300}{16}

\%\text{Decrease in green beans after 3 hours}=18.75\%

Therefore, the correct option is A.
