Volume of cone: pi * r^2 * h/3
Given volume, height

942in^3 = 3.14 * r^2 * 9/3
942in^2 = r^2 * 9.42
Divide by 9.42
r^2 = 100, r = -10, 10
Cannot be negative so...

Solution: radius is 10 in.

Triangle abc is similar to triangle qrs. what is the length of rq

aivan3 [116]

If the two triangles are similar, then the corresponding parts of congruent triangles are congruent.

That means that the length of RQ is the same as the corresponding side from triangle ABC.

Hope this helps :)

A farmer is building a fence to enclose a rectangular area consisting of two separate regions. The four walls and one additional

Vlad [161]

Answer:

The maximal area will be "1093.5 square feet".

Step-by-step explanation:

Let,

Length = L feet

Breadth = b feet

Given Total fencing = 162 feet

According to the question,

$(2\times L)+(3\times b)=162$

$2L+3B=162$

$L=\frac{162-3b}{2}$

$L=81-\frac{3}{2}b$

As we know,

$Area=Length\times breadth$

$=(81-\frac{3}{2}b)\times b$

$=81b-\frac{3}{2}b^2$

Now, we required to decrease or minimize the are. So for extreme points:

$\frac{dA}{db}=0$

or,

$\frac{dA}{dB}=\frac{d}{db}(81-\frac{3}{2}b^2 )=0$

$81-\frac{3}{2}\times 2\times b=0$

$b=\frac{81}{3}$

$b=27 \ feet$

Now on putting the value of b, we get

$l=81-\frac{3}{2}\times 27$

$=81-40.5$

$=40.5 \ feet\\$

So that the dimensions will be:

⇒ 40.5 feet by 27 feet

Therefore when the dimension are above then the area will be:

= $81\times 27-\frac{3}{2}\times 27\times 27$

= $2187-\frac{3}{2}\times 729$

= $2187-1093.5$

= $1093.5 \ square \ feet$
