Answer:

Lateral surface area of the cylinder= $376.8feet^2$

Step-by-step explanation:

Lateral surface area of the cylinder is the area of the side wall excluding its top and the bottom:

Radius=10 feet

Height=6 feet

Lateral surface area of the cylinder = $2\pi rh$

As, $\pi =\frac{22}{7}= 3.14$

Putting the values in the formula:

L.S.A of the cylinder= $2*3.14*10*6$

$=2*3.14*60\\\\=120*3.14\\\\=376.8feet^2$

Lateral surface area of the cylinder= $376.8feet^2$

If a=under root s(s-a)(s-b)(s-c) then the value of a, when a =3 b =4c = 5 and s =a+b+c by 2

kramer

Answer:

6

Step-by-step explanation:

Here it's given that ,

$\sf\red{\longrightarrow} A=\sqrt{s(s-a)(s-b)(s-c)}$

Also ,

$\sf\red{\longrightarrow} s =\dfrac{a+b+c}{2}$

And we need to find out the value of A , when

a = 3
b = 4
c = 5

So , on substituting the respective values to find s we have ,

$\sf\red{\longrightarrow} s =\dfrac{3+4+5}{2}=\dfrac{12}{2}=\bf{6}$

Now let's find out A as ,

$\sf\red{\longrightarrow} A = \sqrt{6(6-3)(6-4)(6-5)} \\$

$\sf\red{\longrightarrow}A =\sqrt{6 * 3 * 2 * 1}\\$

$\sf\red{\longrightarrow} A = \sqrt{3^2 * 2^2 *1^2}\\$

$\sf\red{\longrightarrow}A = 3*2\\$

$\sf\red{\longrightarrow}\boxed{\qquad \blue{\bf A = 6 \qquad}}$

Complete the following statement.

Svetradugi [14.3K]

Answer:

if $p ( x ) = x^2 + 7 x + 3$ is divided by $x + 4$ , the remainder is -9

Step-by-step explanation:

We need to find the remainder if $p ( x ) = x^2 + 7 x + 3$ is divided by $x + 4$

Dividing $p ( x ) = x^2 + 7 x + 3$ by $x + 4$

The division is shown in figure attached.

The remainder = -9

The quotient = x+3

So, if $p ( x ) = x^2 + 7 x + 3$ is divided by $x + 4$ , the remainder is -9

A manager needs to rope off a rectangular section for a private party. The length of the section must be 7.6 meters. The manager

Andrew [12]

Answer:

$W\leq 6.4\ m$

Step-by-step explanation:

we know that

The perimeter of a rectangle is equal to

$P=2(L+W)$

we know that

$L=7.6\ m$

$P\leq28\ m$

substitute

$2(7.6+W)\leq28$

solve for W

$(7.6+W)\leq14$

$W\leq14-7.6$

$W\leq 6.4\ m$

Write a linear equation in point-slope form for the line that goes through (1, -3) and (3,9).

dimaraw [331]

The slope of the line is 6, meaning that you can eliminate A,C. Since the point slope formula is y-y1=m(x-x1) you just need to see if the points are correct.

B. (3,9)
D. (1,-3)

While these do contain one point, substitute the coordinates to see which contain both.

B.

(1,-3): -3-9=6(1-3): -12=-12
(3,9): 9-9=6(9-3): 0= 6(6)

D.

(1,-3): -3+3=6(1-1): 0=6(0); 0=0
(3,9): 9+3=6(3-1): 12=6(2): 12=12

D is correct since the coordinate are on the line.
