1 answer:

8 0

$\text {Volume =} \dfrac{1}{3} \pi r^{2} h$

$\text {Volume =} \dfrac{1}{3} \pi (6)^{2} (9)$

$\text {Volume =} 339.29 \ yd^3$

Instructions: Find the missing side. Round your answer to the<br> nearest tenth

zhuklara [117]

Answer:

Step-by-step explanation:

To find x we use cosine

That's

cos ∅ = adjacent / hypotenuse

From the question

The adjacent is x

The hypotenuse is 28

So we have

cos 43 = x / 28

x = 28 cos 43

x = 20.477

x = 20 to the nearest tenth

Hope this helps you

Find the exact circumference of the circle. please help?<br>

Bogdan [553]

Answer:

3rd option

Step-by-step explanation:

We first need to find the diameter of the circle.

We know this is a square because all sides are marked by a line so this means they are equal. Let find the diagonal of the square to find all parts of the square.

The diagonal of a square is

$a \sqrt{2}$

where a is the side lengths of the square.

So this means the diagonal of the square is

$18 \sqrt{2}$

The diagonal is also the diameter of the main circle. The formula for circumference is

$d\pi$

where d is the diameter.

So the diameter is

$(18 \sqrt{2} )\pi$

$18\pi \sqrt{2}$

The third option is correct

A cylinder has volume 78 cm³. What is the volume of a cone with the same radius and height?

OleMash [197]

Answer:

The volume of the cone is $26\ cm^{3}$

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

$V=\pi r^{2}h$

In this problem we have that

$V=78\ cm^{3}$

$78=\pi r^{2}h$ -----> equation A

The volume of a cone with the same radius and height is equal to

$V=\frac{1}{3}(\pi r^{2}h)$ -----> equation B

Substitute equation A in equation B

$V=\frac{1}{3}(78)$

$V=26\ cm^{3}$

Mai biked 6\frac{3}{4} miles today, and Noah biked 4\frac{1}{2} miles.

Alinara [238K]

It was 1.5 times the length of Noah's bike ride as Mai’s bike ride.

The problem we dealing with is related to mixed numbers which are referred to as mixed numbers and could be the whole number, and a proper division spoke together. It for the most part speaks to a number between any two whole numbers.

Since we are providing mai's rate which is 6 3/4 miles and Noah's rate of 4 1/2 miles, So in order to find the time the length of Noah's ride is compared to Mal's, we just need to divide the given rates by each other

=> 6 3/4 divided by 4 1/2,

=> 27/4 divided by 9/2, (The result is an improper fractions)

=> 27/4 X 2/9

=>3/2

=> 1.5
