What the closest volume of a cylinder with a height of 10 and a circumference of 8

Mathematics
1 answer:
jenyasd209 [6]1 year ago
3 0

In order to calculate the volume of a cylinder, we can use the following formula:

V=\pi r^2h

Where r is the base radius and h is the height.

If the circumference is 8, we have:

\begin{gathered} C=2\pi r \\ 8=2\pi r \\ r=\frac{4}{\pi} \end{gathered}

Now, calculating the volume, we have:

\begin{gathered} V=\pi(\frac{4}{\pi})^2\cdot10 \\ V=\frac{160}{\pi} \\ V=50.93 \end{gathered}

So the correct option is the second one.

Solve the equation 5n+7=21
Simora [160]

Answer:

Hi there, I believe the answer to this equation is: 2.8

Step-by-step explanation:

Subtract 7 on both sides so

5n+7=21-7

you are left with 5n=14 you need to get n by itself so divide 5 on both sides.

5n/5 = 14/5

n=2.8

Hope this is correct :)

Have a great day

A 13.5-meter ladder leans against a brick wall and the ladder makes a 75∘ with the wall. The distance d the ladder goes up the w
Alex73 [517]

Answer:

3.5 m

Step-by-step explanation:

Use Pythagorean theorem to find the distance (d) the distance goes up the wall = adjacent to the angle 75° that is formed with the wall.

Length of ladder = the hypothenuse = 13.5 m

Thus, we would use:

Cos75 = adjacent/hypothenuse

Cos 75 = d/13.5

Multiply both sides by 13.5

13.5*cos(75) = d

13.5*0.2588 = d

3.4938 = d

d ≈ 3.5 m (nearest tenth)
