\bf \begin{array}{ccll} ft^2&minute\\ \cline{1-2} 50&\frac{1}{5}\\\\ x&6 \end{array}\implies \cfrac{50}{x}=\cfrac{~~\frac{1}{5}~~}{6}\implies \cfrac{50}{x}=\cfrac{~~\frac{1}{5}~~}{\frac{6}{1}}\implies \cfrac{50}{x}=\cfrac{1}{5}\cdot \cfrac{1}{6} \\\\\\ \cfrac{50}{x}=\cfrac{1}{30}\implies 1500=x

Answer:

60 square feet.

Step-by-step explanation:

Given  : a water pipe leak floods 50 square feet every 1/5 minute.

To find :  what is the flooded area after 6 minutes.

Solution : We have given

In \frac{1}{5} minute water pipe leak flood = 50 square feet.

In 1 minute water pipe leak flood = 50 * \frac{1}{5].

In 1 minute water pipe leak flood = 50 * \frac{1}{5}* 6 square feet.

In 1 minute water pipe leak flood = 10 * 6 square feet.

In 1 minute water pipe leak flood = 60 square feet.

Therefore,

60 square feet.

Find the volume of the cone. Use 3.14 for π. Round to the nearest tenth.
Leviafan [203]

Volume\,\,of\,\,cone=1527.1\,\,cm^3

So, Option C is correct.

Step-by-step explanation:

We need to find Volume of cone.

We are given:

π = 3.14

Length = 27 cm

Diameter = 15 cm

The formula used to find Volume of cone is:

Volume\,\,of\,\,cone=\frac{1}{3}\pi  r^2h

We are given diameter but we need radius in the formula

So, Radius = Diameter/2 = 15/2 = 7.5 cm

We need to find height of cone.

Using Pythagoras theorem:

h^2=p^2+b^2\\ (27)^2=p^2+(7.5)^2\\729=p^2+56.25\\p^2=729-56.25\\p^2=672.75\\Taking\,\,square\,\,root:\\p=25.93

So, Height of cone = p= 25.93

So, r= 7.5 and h= 25.93 and π = 3.14

Putting values in the formula:

Volume\,\,of\,\,cone=\frac{1}{3}3.14*(7.5)^2*25.93

Volume\,\,of\,\,cone=1526.62

Rounding off to the nearest tenth:

Volume\,\,of\,\,cone=1527.1\,\,cm^3

So, Option C is correct.
