Consider a cylinder with a radius of 6 ft and height of 11.5

1 answer:

6 0

The formula for a cylinder V= pi r squared times the height. I should suppose you were told to abbreviate pi to 3.14. First do 6 to the power of 2 which is 36 then multiply it by 3.14 witch would be 113.04. Then multiply that by 11.5 which would be 1299.96

The answer is 1299.96

What two numbers multiply to 16 and add to 4?

alukav5142 [94]

You said that (xy) = 16, and (x+y) = 4 .

From the second equation you can get [ x = 4 - y ],
then substitude that for 'x' in the first equation, and
finally, rearrange the first equation to read
 x² - 4x + 16 = 0

Don't even try to factor that quadratic equation. Go straight
to the quadratic formula, and the two solutions you find are ...

 x = 2 + i 2√3
and
 x = 2 - i 2√3 .

Those are the two number that do what you want.

There are no real numbers that can do it.

Farmer brown has ostriches and llamas. Altogether she counts 98 feet and 33 heads. How many ostriches does she have?

Ronch [10]

Answer: She has 17 ostriches.

Step-by-step explanation:

We know , ostrich has 2 legs where as llama has 4 legs.

Let x be the number of ostriches and y be the number of llamas.

Then, as per given , we have the following linear equations :

$2x+4y=98---(i)\\\\ x+y=33---(ii)$
