How do i find the volume of a cylinder?

Hi there! The answer is 226 in^3

Like you've already written it down, the formula of the volume of a cylinder is
volume \: = \: base \: \times \: height

Since the base of any cylinder is a circle, we can find the area of this circle with the formula
a \: = \pi \: {r}^{2}
With r representing the radius.

Therefore, the volume of any cylinder can be found with the formula
v \: = \pi \: {r}^{2} \: h
With h representing the height.

Filling in this formula gives us the following
v \: = \pi \times {3}^{2} \times 8 = 226.08
Hence, the volume of this cylinder is about 226 in ^ 3.

A cafe sells puffs. 5/9 are beef and 1/3 are chicken. The remaining 18 are tuna. Calculate 1. What fraction of the puffs are tun
Ksivusya [100]
Let n be the total number of puffs. Now we can write:
n=\frac{5}{9}n+\frac{1}{3}n+18
Adding the fractional value of n, we get:
n=\frac{5+3}{9}n+18
Simplifying and rearranging gives us:
n-\frac{8}{9}n=18
Therefore we can simplify to get:
\frac{1}{9}n=18
and finally
n=18\times9=?
The fraction of the puff that are tuna is found from:
\frac{18}{18\times9}=\frac{1}{9}

What is the directrix of the parabola defined by `(1)/(4)(y + 3) = (x − 2)^2`?
Sauron [17]

The directrix of the parabola is y =  \frac {-49}{16}

<h3>How to determine the equation of the directrix?</h3>

The parabola equation is given as:

\frac 14(y + 3) = (x -2)^2

A parabola is represented as:

4p(y - k) =(x -h)^2

By comparing both equations, we have:

4p = 1/4 ==> p = 1/16

-k= 3 ==> k = -3

The directrix is represented as:

y = k - p

So, we have:

y = -3 - \frac 1{16}

Take the LCM

y =  \frac {-16 * 3- 1}{16}

Evaluate

y =  \frac {-49}{16}

Hence, the directrix of the parabola is y =  \frac {-49}{16}
