Answer:

121.9

Step-by-step explanation:

I will use pi but not in the answer

use formula V=πr²h

(π)(3.5²)(5.5)

12.25 × 5.5=67.375 × π=211.6648...

1/2(4/3(π(3.5³))

4/3(42.875)=57.166...× π = 179.59438...

1/2(179.59438...) = 89.79719...

211.6648... - 89.79719... = 121.86761... ≈ 121.9

What is 16% of 43 minutes? Round answer to tenths place.

sergiy2304 [10]

Answer: $6.9\ minutes$

Step-by-step explanation:

Let "x" represents the 16% of 43 minutes.

Once you analize the information given in the exercise, you can identify that 43 minutes is the 100%.

Then, with this data, you can set up the following proportion:

$\frac{100}{43}=\frac{16}{x}$

Now you must solve for "x". The steps are:

- Multiply both sides of the equation by "x"

$(x)(\frac{100}{43})=(\frac{16}{x})(x)\\\\\frac{100x}{43}=16$

- Multiply both sides by 43:

$(43)(\frac{100x}{43})=(16)(43)\\\\100x=688$

- Divide both sides by 100:

$\frac{100x}{100}=\frac{688}{100}\\\\x=6.88$

- Rounding to the tenths place:

$x\approx6.9$

What is 40 percent of 35

Murrr4er [49]

Hey there!

You can figure this out by making 40% into a decimal. This decimal would be .4. So multiply 35 by .4. You get 14. So 14 is 40 percent of 35.

I hope this helps!
