V = πr²h
V = (3.14)(5)²(16)
V = (3.14)(25)(16)
V = 1256

Hope this helps :)

Answer:

(28*12)-(18*5) or 246 meters squared

Step-by-step explanation:

It is actually easy really, all you have to do is find the area of the larger polygon (28*12) or 336 and subtract the smaller polygon (18*5) or 90 and subtract it from the larger polygon getting you 246 meters squared

The perimeter of a square patio is (8x - 28). What is the length of one side?

astraxan [27]

Answer:

Length is 7, Permimeter is 28

Step-by-step explanation:

Perimeter=4×side

(8x-28)=4×x [let length be x]

8x-28=4x

8x-4x=28

4x=28

x=28÷4

x=7

Length = x = 7

Perimeter=(8x-28)

=(7×8)-28

=56-28

=28

What’s the answer to this equation?

Tresset [83]

Answer:

Part A) The graph in the attached figure

Part B) see the explanation

Step-by-step explanation:

Part A) Graph the function

we have the quadratic function

$y=3x^2-12x-36$

This is a vertical parabola open upward

The vertex is a minimum

using a graphing tool

The graph in the attached figure

Part B) What are the values of a, b and c?

we know that

The values of a and b represent the x-intercepts of the quadratic equation

The x-intercepts are

(-2,0) and (6,0)

$a=-2\\b=6$

Find the value of c

we know that

The x-coordinate of the vertex in a vertical parabola is equal to the midpoint of the roots

The value of c is equal to

$c=\frac{a+b}{2}$

substitute the given values

$c=\frac{-2+6}{2}=2$

see the attached figure
